Don't remove android:largeHeap="true"!

Answer 2

stream = activity.getContentResolver().openInputStream(uri);
BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.RGB_565;

bitmap = BitmapFactory.decodeStream(stream, null, options);
int Height = bitmap.getHeight();
int Width = bitmap.getWidth();
enter code here
int newHeight = 1000;
float scaleFactor = ((float) newHeight) / Height;
float newWidth = Width * scaleFactor;

float scaleWidth = scaleFactor;
float scaleHeight = scaleFactor;
Matrix matrix = new Matrix();
matrix.postScale(scaleWidth, scaleHeight);
resizedBitmap= Bitmap.createBitmap(bitmap, 0, 0,Width, Height, matrix, true);
bitmap.recycle();

Then in Appliaction tag, add largeheapsize="true

have you tried adding this to your manifest under applications? android:largeHeap="true"?

like this

  <application
      android:name=".ParaseApplication"
      android:allowBackup="true"
      android:icon="@mipmap/ic_launcher"
      android:label="@string/app_name"
      android:theme="@style/AppTheme"
      android:largeHeap="true" >

I had the problem too.

Same with most of others above. The problem is caused by huge image.

Just resize some images, and no need to change any code.

My problem solved after adding

 dexOptions {
        incremental true
        javaMaxHeapSize "4g"
        preDexLibraries true
        dexInProcess = true
    }

in Build.Gradle file

I ran into this problem when I didn't kill off my old activity when moving on to a new activity. I fixed it with finish();

    Intent goToMain = new Intent(this,MainActivity.class);
    startActivity(goToMain);
    finish();
