I've found some opensource document scanner app, first (default) "DocumentScannerActivity" of this app is a camera for capturing images of documents for further processing. Works good, without any error.
Then I've add my own (new) "MainActivity" as default with button inside, with onclick listener that opens "DocumentScannerActivity":
scanActivityBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, DocumentScannerActivity.class);
startActivity(intent);
}
});
This code opens "DocumentScannerActivity", but after pressing on "Capture image" application crashes with error:
java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String android.net.Uri.toString()' on a null object reference
at az.deep.archiverabitabank.DocumentScannerActivity.saveDocument(DocumentScannerActivity.java:1042)

at android.os.Looper.loop(Looper.java:172)
at android.os.HandlerThread.run(HandlerThread.java:65)
Here is the problematic part of code (app tries to save captured image to storage) in DocumentScannerActivity:
Uri fileUri = null;
if (intent.getAction().equals("android.media.action.IMAGE_CAPTURE")) {
fileUri = ((Uri) intent.getParcelableExtra(MediaStore.EXTRA_OUTPUT));
Log.d(TAG, "intent uri: " + fileUri.toString()); //LINE 1042, where error occurs
try {
fileName = File.createTempFile("onsFile", ".jpg", this.getCacheDir()).getPath();
} catch (IOException e) {
e.printStackTrace();
return;
}
isIntent = true;
}
Here is the related cut from AndroidManifest.xml:

What I'm doing wrong, how to prevent this error?

I've created a custom deep link dispatcher in Java within a react native project.
The issue I'm having is that I can't get MainActivity to start from my dispatcher, and I can't quite figure out why.
I have AndroidManifest set up so that the deep link is captured in LinkDispatcherActivity effectively, but the startActivity(dispatchedIntent) never reaches MainActivity, which is where I assume it needs to go. Ordinarily in AndroidManifest.xml, deep links would be sent to MainActivity).
It does open the app, but I assume it's because LinkDispatcherActivity is part of the app? Not sure, if I say something dumb it's because this is only my 3rd day in a row writing Java π°
Below is my code.
package com.example.app;
//Inspired by https://github.com/justeat/Android.Samples.Deeplinks, Licensed under Apache 2.0
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;
import net.openid.appauth.RedirectUriReceiverActivity;
public class LinkDispatcherActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
try {
dispatchIntent(getIntent());
} catch (IllegalArgumentException iae) {
// Malformed URL
if (BuildConfig.DEBUG) {
Log.e("Deep links", "Invalid URI", iae);
}
} finally {
// Always finish the activity so that it doesn't stay in our history
finish();
}
}
public void dispatchIntent(Intent intent) {
final Uri uri = intent.getData();
final String host = uri.getHost().toLowerCase();
if (uri == null) throw new IllegalArgumentException("Uri cannot be null");
// Default intent
Intent dispatchedIntent = new Intent(LinkDispatcherActivity.this, MainActivity.class);
dispatchedIntent.setData(uri);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
Log.d(dispatchedIntent.getDataString(), "dispatchIntent: intent string");
// Auth intent only, this is why I need the dispatcher
if ("login".equals(host)) {
dispatchedIntent = new Intent(this, RedirectUriReceiverActivity.class);
dispatchedIntent.putExtra("requestCode", 0);
Log.d("Login", "mapAppLink: ");
startActivityForResult(dispatchedIntent, 0);
return;
}
Log.d("Default", "mapAppLink: ");
startActivity(dispatchedIntent);
}
}

Edit: for the intent, I've tried:
new Intent(getApplicationContext(), MainActivity.class)
new Intent(reactContext, MainActivity.class) (extending ReactActivity instead of Activity)
new Intent(this, MainActivity.class)
new Intent("MainActivity")
Try adding RedirectUriReceiverActivity to the manifest - I couldn't see it in there.
<activity android:name="com.facebook.react.devsupport.RedirectUriReceiverActivity" />
This is what I ended up with for the LinkDispatcherActivity. To summarize, what I did was dispatch the intents that the deep activities were eventually supposed to invoke directly, instead of trying to forward the intent. In other words, if you're trying to pass an intent from one activity to another, maybe don't and consider dispatching the activity/function/intent that you want to run afterwards. I still think forwarding the intent should have worked, but this is what ended up working.
In order to accomplish the above, I:
Called a function within the AppAuth package that generates an intent, and dispatch it
Used ReactContext to emit the url listener event that React Native uses to respond to deep links.

The stack trace clearly indicates that the call to intent.getData() at line 44 of your MainActivity is returning a null. You should check for the null, and not try to interrogate the Intent if it is null.
You could store string data in a static variable, and then check to see if it's null. If it's null use the static data. I know static variables are frowned upon and you should address the root problem, but this will fix your immediate problem.
static String yourStaticString;
...
String data;
if (intent.getData()==NULL)
{
data = yourStaticString;
}
else
{
if (intent.getData().getLastPathSegment()!=NULL)
{
data = intent.getData().getLastPathSegment();
yourStaticString = data;
} else return;
}
I need to keep the screen in portrait mode. For this I use this line in the manifest file
android:screenOrientation="portrait"
Here my file

android:label="#string/app_name"
android:screenOrientation="portrait">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
I use a Samsung S5, and it still can rotate in landscape...
Accorging documentation with Android 5.0 we get wide setting options
android:screenOrientation=["unspecified" | "behind" |
"landscape" | "portrait" |
"reverseLandscape" | "reversePortrait" |
"sensorLandscape" | "sensorPortrait" |
"userLandscape" | "userPortrait" |
"sensor" | "fullSensor" | "nosensor" |
"user" | "fullUser" | "locked"]
I have tried some of them but it still rotate...
What am I doing wrong?

I want to sync a txt file in android internal storage (or sdcard for that matter) and have it automatically sync to a txt in my dropbox. i've used dropbox api but don't have hold on on how to achieve this. help needed please.
Update:
Here's my function to get the txt content to LogCat for now:
public void getFromDbx(){

// Create DbxFileSystem for synchronized file access.
DbxFileSystem dbxFs = DbxFileSystem.forAccount(mDbxAcctMgr.getLinkedAccount());
// Print the contents of the root folder. This will block until we can
// sync metadata the first time.
//dont need this code -- ahmed
// Create a test file only if it doesn't already exist.
if (!dbxFs.exists(testPath)) {
DbxFile testFile = dbxFs.create(testPath);
try {
testFile.writeString(TEST_DATA);
} finally {
testFile.close();
}
}
// Read and print the contents of test file. Since we're not making
// any attempt to wait for the latest version, this may print an

EDIT: there is no error, the app shows the auth screen, I click allow and then nothing happens. I can press allow 10 times and nothing happens at all..
In getFromDbx, you call startLink, which brings up the UI to link an account. When that succeeds, your onActivityResult is executed, where you call getFromDbx, which calls startLink again. :-) Looks like an infinite loop to me.
I've been struggling with this error for a lot and I just gave up. Every time I try to send a message using GCM this error appears on LogCat. What I'm failing to do? I've followed Android examples to set up GCM Notifications.
This is the LogCat Error
Edit: The message actually gets through but I don't think this error is normal.

Fixed, you just need to add setResultCode(Activity.RESULT_OK); at the end of the onReceive(); method
