I have an Intent to share a image from an view. It works, but once I canceled it to upload it on Instagram and I received an exception.
Google didn't help...
Intent
if(!getStringName().equals(" ")) {//check if it is usefull
LinearLayout table=(LinearLayout) findViewById(R.id.table_linear);
table.setDrawingCacheEnabled(true);
Bitmap bitmap = table.getDrawingCache();
String imagepath=saveBitmap(bitmap);
//sv.setDrawingCacheEnabled(false);
Intent shareImage=new Intent();
shareImage.setAction(Intent.ACTION_SEND);
shareImage.setType("image/png");
shareImage.putExtra(Intent.EXTRA_SUBJECT, getString(R.string.app_name));
shareImage.putExtra(Intent.EXTRA_TEXT, getStringName());
shareImage.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(new File(imagepath)));
startActivity(shareImage);
//new RalaAlertToast(context, getString(R.string.share_success), false);
}else {
//show message, that it's not useful
}

Code with error:
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("http://m.fretebras.com.br/fretes"));
startActivity(i);
The error occurs in versions 6.0.1 android, I have no idea why it's happening, I believe that by passing the url to Intent is all right. Can someone help me?
Seems like no browser installed on your phone. Please verify and to avoid crash use below code.
try {
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("http://m.fretebras.com.br/fretes"));
startActivity(i);
} catch (ActivityNotFoundException e) {
e.printStackTrace();
}
Note - This code will just ignore your crash, if no browser found.
I'm trying to implement twitter login in my android app.

Any idea? I'm loosing too much time on this :(
Thank you!
Note: I don't have the twitter app installed. It's supposed to work in a webview.
Found the issue with the first exception. Apparently there are two different problems.
In my AndroidManifest.xml I was missing the attribute android:icon in <application ...>
I hope this will help others.
This question already has answers here:
Android Camera : data intent returns null
(11 answers)
Closed 8 years ago.
Here's what the app does - User clicks button (to take a picture) on Activity A, the captured image gets set as on an ImageView in Activity A, and then the user clicks a "save" button, which takes him/her to Activity B, where the image they took gets displayed (on an ImageView in Activity B)
In order to do this I am trying to find a way to save the image. I tried many different things, but I keep getting a NullPointerException. Here is my code:
I highlighted the area where I think the error is:
public void onClick(View view) {
switch (view.getId()) {
case R.id.take_picture_button:
takePic = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
if (takePic.resolveActivity(getPackageManager()) != null) {
File photoFile = null;
try {
photoFile = createImageFile(); //so photoFile = the file we created up top
} catch (IOException ex) {
// Error occurred while creating the File
ex.printStackTrace();
}
// Continue only if the File was successfully created
if (photoFile != null) {
**takePic.putExtra(MediaStore.EXTRA_OUTPUT**, //extra_output is just the name of the Intent-extra used to indicate a content resolver Uri to be used to store the requested image or video.
**Uri.fromFile(photoFile));**
startActivityForResult(takePic, cameraData);
}
And here is the code for the onActivityResult
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == cameraData && resultCode == RESULT_OK) {
mReturningWithResult = true;
extras = data.getExtras();
And here is where I set my image view to my captured image (on Activity A)
#Override
protected void onPostResume() {
super.onPostResume();
if (mReturningWithResult) {
foodImage = (Bitmap) extras.get("data");
foodImageView.setImageBitmap(foodImage);
}
mReturningWithResult = false;//resetting it for next time
}
Here is the logcat (sorry I'm new to this)

Do you guys know a way I can fix this? Thank you!
You are passing MediaStore.EXTRA_OUTPUT, in which case, the intent field in onActivityResult can be null.
The solution is to just use the photo file you created, and passed as uri in the putExtra
So instead of trying to get the photo file location from the intent, just use Uri.fromFile(photoFile)
replace
extras = data.getExtras();
...
with
`Uri.fromFile(photoFile)`
or just use photoFile if that is what you want...just dont rely on intent data

Thx !
Normally, the above code is called inside onStart/OnResume method or after these methods, not inside onStop/onSaveInstance. You are trying to do some operation after activity is getting killed. Perform serivcesConnected call before onStop/finish/saveInstances method call.
I'm having a problem, and I already tried everything I found on this site, it's not helping, so I'm asking this question myself.
my code is:
public class MyActivity extends Activity{
protected PositionSense positionSense;
protected Preferences preferences;
String IP;
String ID;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
positionSense = new PositionSense(this, null);
SharedPreferences settings = getSharedPreferences("preferences", 0);
IP = settings.getString("ip", "http://192.168.1.3:8080/servlet");
ID = settings.getString("id", "USER");
}
Later on, I use these variables in a background running thread that contacts the servlet and sends some info (including position and ID of the user which is saved in preferences)
I'm not posting all of that because I don't want to clog up the thread more than necessary (but if it is needed, I will post it all)
In any case, it doesn't work and it gives me the following error log:
09-14 16:47:20.854: WARN/dalvikvm(552): threadid=1: thread exiting with uncaught exception (group=0x409c01f8)

I don't know what to do about it.
Can someone give me the SIMPLEST possible way to save 2 strings in preferences in one activity that are used in some other activity within the same application? It's supposed to be really simple, but I simply cannot make it work, and I'm nearing my deadline.
Thanks!
To save to shared preferences you can try:
String ip = "192.168.1.1";
SharedPreferences prefs = getSharedPreferences("IP", Context.MODE_PRIVATE);
prefs.edit().putString("Sample IP", ip).commit();
To get the information from the shared preferences you can try:
String newIP = prefs.getString("Sample IP");//You can also place a default value if needed; to bypass the null character.
Now to pass them into activities you can try doing an intent call like below
**Activity One
Intent intent = new Intent(getApplicationContext(),SecondActivity.class);
intent.putExtra("IP",newIp);
startActivity(intent);
**Activity Two
Bundle extras = intent.getExtras();
String tmp = extras.getString("IP");
Also you can use this link to reference.
