How to fix OutOfMemoryError exception in android?

Question

I am new to android development in fact. I have an android app dealing with large length of list and each list item has bitmap thumbnail. The app load the entire database so it is clearly not efficient. But for now I can't code it again efficiently because it will spend much time and also can't use try and catch because I don't know where this exception will occur. I just want to know another simple solution such as android:largeHeap="true", dexOption in app.gradle or org.gradle.jvmargs=-Xmx4096m -XX:MaxPermSize=4096m -XX:+HeapDumpOnOutOfMemoryError in gradle.property.

I tried them but nothing is improved.

OutOfMemoryError with large bitmaps is a known issue in Android.

You need to handle it in your source code. Tweaking the Manifest file settings is not the solution.

Here an example how to deal with large bitmaps.
