I think that the problem is the autocompletetextview i created. I mapped the array to get the position of array when i click in the dropdown during type what i want search.
At line 88 i have this:
ArrayMap<String, Integer>myArrayMap = new ArrayMap<String, Integer>();
The crash seems to be only with android 4.1 version. Is there any incompatibility?

ArrayMap was introduced in Api level 19, but it was also released in the compatibility library v4, so it would be enough to change the import to android.support.v4.util.ArrayMap instead of android.util.ArrayMap

For now it migrates to AndroidX.
Instead of android.util.ArrayMap you will write androidx.collection.ArrayMap

java.lang.ClassCastException: android.view.ViewGroup$LayoutParams cannot be cast to android.widget.LinearLayout$LayoutParams android 4.1.2

I have this Exception only on some devices on android 4.1.2. So, I want to know what is the problem it can be.
Here is stack trace - no one line from my code, only from SDK - exception happens in SDK, so no lines were missed:

In your code you are importing import android.widget.LinearLayout.LayoutParams instead of android.view.ViewGroup.LayoutParams;
so Delete import android.widget.LinearLayout.LayoutParams;
and Add import android.view.ViewGroup.LayoutParams;

Android: Having force close when accessing the media store

I seems to receive a force close when turning off the phone and turning back on and when I on to the application which require to load the photos with media store , it force close. It has no problem when I wait for awhile before going to the application. Do I need to check anything before using the media store.
The error below may or may not related I don't actually sure.

SECOND UPDATE
the errored line in question is the second of
final Drawable d = getDrawable();
final int origW = d.getIntrinsicWidth();
final int origH = d.getIntrinsicHeight();
The complete code is here on stack overflow at Trying to get the display size of an image in an ImageView . It's the response with the most votes.

Make sure you have provided the right constructor for the XML. Your custom Views constructor should have the following method signature:
public SizeAwareImageView(Context context, AttributeSet attrs){
// todo
}
I'm guessing it currently looks like this:
public SizeAwareImageView(Context context){
// todo
}
Also I'd double check you meant to set the XML parameter android:background, for ImageView you actually set android:src.

Probably you have an error in the layout file called here:

Please check it yourself, or post it here.

I removed Gen folder and then again clean and build project and the error has gone.

Same, error went away after a clean project and do a rebuild.
