A week ago, I was successfully using ListView, adding an item to it every time a button is clicked. Then I found I needed to put something in a thread separate from the main UI thread, and somewhere along the way, something broke.
Now I'm seeing an error every time I start Android Studio, saying FileNotFoundException: Entry fileTemplates//code/Google Test Fixture SetUp Method.cc.ft not found in E:/Programs/Android Studio/lib/idea.jar I go to that very folder though, and I can see that the file exists. This is the closest I've come to figuring out how to fix it.
I've also tried a cold reboot of both my computer and my phone, reinstalling Android Studio, creating a brand new project, and File > Invalidate Caches and Restart, none of which were helpful.
The only other answers I can find say it's because of being a 64 bit version on a 32 bit system. I am certain that's not the case, unless I somehow downloaded 64 bit while specifically looking for 32 bit.
I have no idea whether it's a problem with Android Studio, Gradle, something to do with the phone I'm using as a testing platform, or what.
I'm using:
Windows 8.1 Pro (32-bit)
2x Pentium 3.2 GHz (x64)
Android Studio 2.3.3
minimum SDK of API 15: Android 4.0.3 IceCreamSandwich
Java v1.8.0_144 (according to "java -version" in a command prompt)
Java 8 updates 60 and 144 are in my list of installed programs, along with Java SE Development Kit 8 updates 60 and 144
Here's the code from the fresh project that I mentioned:
MainActivity.java
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import java.util.ArrayList;
public class MainActivity extends AppCompatActivity {
ArrayList<String> listItems;
ArrayAdapter<String> adapter;
ListView listview = (ListView) findViewById(R.id.listview);
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listItems = new ArrayList<>();
adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, listItems);
listview.setAdapter(adapter);
}
public void sendAnother(View view) {
adapter.add("button clicked");
}
}

It turns out, all I was doing wrong was trying to initialize listview before onCreate(). Declaring it is fine, but initializing breaks it. I guess, despite being defined in the xml, View objects aren't instantiated until runtime?
I have a backup I had made from before anything broke, but it was also broken. Or, now that I'm messing with it again, partially broken. (button doesn't work, but I can output to the listview) I suppose I took this to mean something within Android Studio might have been broken. I think that's why I didn't notice the difference in where I tried to initialize listview.
I guess any rock will break if you hit it long enough with a hammer, eh?
So due to memory issue I thought about using Facebook's Fresco library.
So this is what I did,
First I added the following dependencies,
compile 'com.facebook.fresco:fresco:1.3.0'
compile 'com.facebook.fresco:animated-gif:1.3.0'
Then I initialized it in application class,
Fresco.initialize(getApplicationContext());
Then I added SimpleDraweeView to layout file,
<com.facebook.drawee.view.SimpleDraweeView
android:id="#+id/imageMessage"
android:layout_width="180dp"
android:layout_height="180dp"
/>
Then I added the code in my activity,
SimpleDraweeView gif = (SimpleDraweeView) row.findViewById(R.id.imageMessage);
ImageRequest request = ImageRequestBuilder.newBuilderWithSource (Uri.parse(url.get(position)))
.setProgressiveRenderingEnabled (true)
.build ();
DraweeController controller = Fresco.newDraweeControllerBuilder ()
.setImageRequest (request)
.setAutoPlayAnimations (true)
.build ();
gif.setController (controller);
But it's not loading images, I also tried different urls but same result, So what I'm missing...
i was facing same issue but not with gif. below is the code which load images, don't forget to initialize fresco.
Fresco.initialize(context);
SimpleDraweeView iv_image = (SimpleDraweeView)itemView.findViewById(R.id.iv_image);
iv_image.setImageURI(Uri.parse("your image url here"));
`
and here is xml
<com.facebook.drawee.view.SimpleDraweeView
android:id="#+id/iv_image"
android:layout_width="match_parent"
android:layout_height="wrap_content"
fresco:actualImageScaleType="centerCrop"
fresco:placeholderImage="#drawable/iv_car"
fresco:viewAspectRatio="1.22"/>
I have to say at first that i am new to android programming. I am trying to send simple data (a short string) to a BLE peripheral device via Android. Therefore i customized the BluetoothLeGatt example from
http://developer.android.com/samples/BluetoothLeGatt/project.html
I replaced the Gatt Services List in the gatt_services_characteristics.xml with a text field for incoming data and below a EditText and a "send" button. The code is the following:
<TextView android:id="#+id/gatt_services_list"
android:layout_width="match_parent"
android:layout_height="250dp" />
<EditText android:id="#+id/sendText"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_margin="10dp"
android:layout_below="#id/gatt_services_list"/>
<Button
android:id="#+id/sendButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="SEND"
android:onClick="sendData"/>
I also commented out the function displayGattServices(List gattServices) in DeviceControlActivity.java and wrote a function for the button click as below:
public void sendData(View v) {
value = textField.getText().toString();
byte [] strBytes = value.getBytes();
mGattServicesList.setText(text + "\n>" + value);
text = text + "\n>" + value;
clearUI();
}
I now want to implement a simple way to send the data typed in the EditText. The data just shall be shown in a terminal.
I searched for a solution, but i didn't fully understand the concept of the Gatt Characteristic which i am afraid i have to use for this. I am programming with Android Studio 1.4.1 and using API 18 and higher.
How can i send the data in an easy way?
Thanks in advance
Android BluetoothLeGatt example already customized to Send and Receive via UART. See

I have a Android Webview and when I click on a link to download a file (image of pdf etc) I got a error message.
Error message:
Cannot call determinedVisibility() - never saw a connection for the pid
Any idea what I do wrong? Who can help please!?
Just a bit of configuration:
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setDomStorageEnabled(true);
I got the same error and Burhans solution was not helping me.
I think things went wrong when you´re trying to load different urls too fast.
Edit: Found a better solution credits go to user2652394
WebView must be loaded twice to load correctly
You have to do something like this:
webView.postDelayed(new Runnable() {
#Override
public void run() {
webView.loadUrl(landingpage);
}
}, 500);
I faced the same issue.
Was solved by giving a WebView a static height (ie 300dp) or specifying minHeight value.
This problem in my case produce by incorrect settings in layout properties. I had used:
<WebView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/webView"
android:layout_below="#+id/textView"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="false"
android:layout_alignWithParentIfMissing="false" />
Instead of setting:
<WebView
android:id="#+id/webView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#+id/textView" />
The problems had been solved, when I removed "layout_alignParent" settings.
Background
Here is the source code of the method in the browser engine that gives the error (BindingManagerImpl.java), from Chromium source:
#Override
public void determinedVisibility(int pid) {
ManagedConnection managedConnection;
synchronized (mManagedConnections) {
managedConnection = mManagedConnections.get(pid);
}
if (managedConnection == null) {
Log.w(TAG, "Cannot call determinedVisibility() - never saw a connection for the pid: "
+ "%d", pid);
return;
}
Analysis
It's a rendering warning from content.
Consecutive calls to loadUrl cause a race condition. The problem is that loadUrl("file://..") doesn't complete immediately, and so when you call loadUrl("javascript:..") it will sometimes execute before
the page has loaded.
Detail
For more detail see this stackoverflow answer.
This is how I fixed a similar issue:
mWebView.setWebChromeClient(new WebChromeClient());
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setDomStorageEnabled(true);
mWebView.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view,String url) {
return false;
}
});
mWebView.loadURL(...
Late to party, but might help some.
May sound silly as hell, but the mistake I made was not adding http:// in the beginning of the URL.
Check whether internet permission is properly set on the Manifest file. Make sure that the permission tag should be outside of your Application tag.
<uses-permission android:name="android.permission.INTERNET" />
Hope this might help some one.
I found a workaround by using onPageFinished method instead of shouldOverrideUrlLoading. It also provides the needed URL in the list of arguments.
The only trick is to set a check so that the main logic of the method (in my case making a Toast) is not triggered when onPageFinished gets called on the the page load itself.
mWebView.setDownloadListener(new DownloadListener() {
#Override
public void onDownloadStart(String url, String userAgent, String contentDisposition,
String mimetype, long contentLength) {
Log.d("download",url);
}
});
I faced the same problem. I can fix my issue by giving this code:
webView.postDelayed(new Runnable() {
#Override
public void run() {
webView.loadUrl(url);
}
}, 500);
instead of:
webview.loadUrl(url);
then, set the url starts with https://
I have the following layout (virtually empty):
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/set_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:contentDescription="content desc"
android:orientation="vertical" >
<TextView android:id="#+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello, I am a TextView" />
</LinearLayout>
The Activity class contains the following:
public class TestActivity extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test);
}
}
When I run this on my mobile device I get the following error:
SpannableStringBuilder
SPAN_EXCLUSIVE_EXCLUSIVE spans cannot have a zero length
I have tried this with and without the TextView and the error still remains, I must be doing something fundamentally wrong for such a basic layout to cause this.
Does anyone have any ideas on how I can get this to load without the error?
I have run into the same error entries in LogCat. In my case it's caused by the 3rd party keyboard I am using. When I change it back to Android keyboard, the error entry does not show up any more.
Because the error you're getting is not related to an EditText, then it's not related to your keyboard.
The errors you are getting are not a result of your code; you probably are testing on a Samsung device that has Samsung's TouchWiz.
I had the same errors, then I tested on a Nexus S (also by Samsung, but pure Android OS without TouchWiz) and I didn't get this error.
So, in your case, just ignore these errors while testing on a device! :)
Looking at your code, I'm not sure why you're getting that error, but I had this same error but with EditText fields.
Changing android:inputType="text" (or any of the other inputType text variations) to android:inputType="textNoSuggestions" (or android:inputType="textEmailAddress|textNoSuggestions", for example) fixed it for me.
You can also set this in Code with something like
mInputField.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);
Looks like Android assumes by default that EditText fields will have suggestions. When they don't, it errors. Not 100% confident in that explanation, but the above mentioned changes fixed it for me.
http://developer.android.com/reference/android/text/Spanned.html#SPAN_EXCLUSIVE_EXCLUSIVE
Hope this helps!
On your android phone go to:
settings -> application manager -> all -> samsung keyboard and then click on "clear cache"
(delete all data collected by this application).
Try using the default Android keyboard it will disappear
Make clear you have pass a value in your MainAcitivity for the following methods onCreateOptionsMenu and onCreate
In some cases, the developer deletes the "return super.onCreateOptionsMenu(menu)" statement and changed to "return true".
This worked for me...on every device
<EditText
android:maxLines="1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:textSize="15sp"
android:layout_centerVertical="true"
android:textColor="#000"
android:id="#+id/input_search"
android:background="#null"
android:inputType="text"
android:hint="Enter Address, City or Zip Code"
android:imeOptions="actionSearch"
/>
In Java code:
mSearchText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView textView, int actionId, KeyEvent keyEvent) {
if(actionId == EditorInfo.IME_ACTION_SEARCH
|| actionId == EditorInfo.IME_ACTION_DONE
|| keyEvent.getAction() == KeyEvent.ACTION_DOWN
|| keyEvent.getAction() == KeyEvent.KEYCODE_ENTER){
//execute our method for searching
}
return false;
}
});
I had the same warning and found that removing an unused #id got rid of the warning. For me it was obvious as the #id was associated with a growing list of textViews linked to a database, so there was a warning for each entry.
Masood Moshref is right, this error occur because the option menu of Menu is not well prepared by lacking "return super.onCreateOptionsMenu(menu)" in onCreate() method.
To try to debug this error, first go to your android terminal / console and execute this command:
ps | grep THE_ERROR_PID_YOU_GET_(IT_IS_A_NUMBER)
then if the output comes out as your app... it is your app causing the error. Try to look for empty Strings that you pass into the layout.
I had this exact same problem and it was my fault as I was passing an empty String into my layout. After changing the "" to " " this error went away.
If you don't get your app from the console output, then it is something else causing it (probably, as others said, the android keyboard)
I have faced the same issue. I almost wasted almost couple of weeks to resolved this issue.
Finally I had on doubt on myself and tried to create another project by copy and paste some startup files like SplashScreen & LoginScreen.
But with the same code still i was getting SPAN_EXCLUSIVE_EXCLUSIVE.
Then i have removed the handler code from splash screen and tried again and Wow its working.
I am not getting SPAN_EXCLUSIVE_EXCLUSIVE issue in logcat.
I wondering, why it is? till the time did not get any other solution but by removing handler from splash screen it is working.
Try and update here if it is resolved or not.
Check if you have any element such as button or text view duplicated (copied twice) in the screen where this encounters. I did this unnoticed and had to face the same issue.
I ran into this problem too when I copied some text from the Internet. My solution is to trim the text/remove formatting before doing any further processing.
I had the same problem but with a listView.... i solved it because i was using a wrong R.id.listView that list View needed to have a value, in my case it was strings that i saved on listView2... so the right code was R.id.listView2
I had the same problem then i fixed it by following code!
text = (EditText)findViewById(R.id.TextVoiceeditText);
text.setInputType(InputType.TYPE_CLASS_TEXT|InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);
this error also occurs due to changed API URL. try hitting the URL you are using in postman and c if it's working properly.
rechecking the APIs solved my problem
try avoiding use of view in xml design.I too had the same probem but when I removed the view. its worked perfectly.
like example:
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Username"
android:inputType="number"
android:textColor="#fff" />
<view
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#f9d7db" />
also check and try changing by trial and error android:inputType="number" to android:inputType="text" or better not using it if not required .Sometimes keyboard stuck and gets error in some of the devices.
In my case, the EditText fields with inputType as text / textCapCharacters were casing this error. I noticed this in my logcat whenever I used backspace to completely remove the text typed in any of these fields.
The solution which worked for me was to change the inputType of those fields to textNoSuggestions as this was the most suited type and didn't give me any unwanted errors anymore.
in my case i click on recent apps shortcut on my cell phone and close all apps. This solution always work for me, because this error not related to code.
**DONT PUT SET TEXT IN TEXT WATCHER**etSearch.addTextChangedListener(object : TextWatcher {
override fun afterTextChanged(s: Editable) {
visibleResultList = false
if (s.toString().length != 0) {
getSearchSuggetion(no_of_rec, 0, s.toString())
} else {
// etSearch.setText("")
}
Log.e("text_change","============"+s.toString())
}
override fun beforeTextChanged(s: CharSequence, start: Int, count: Int, after: Int) {}
override fun onTextChanged(s: CharSequence, start: Int, before: Int, count: Int) {
}
})
To solve this problem just add android:usesCleartextTraffic="true" in your AndroidManifest.xml file which is at ..\app\src\main\AndroidManifest.xml just like bellow...
