InputConnection.finishComposingText() NullPointerException

I am getting this error log on crashlytics. I don't know what makes this crash. It occurs on Android 4.x, 5.x, 6.x devices. (Samsung, Sony, LGE etc.)

Fatal Exception: java.lang.NullPointerException: Attempt to invoke interface method 'boolean android.view.inputmethod.InputConnection.finishComposingText()' on a null object reference

The above answer should be correct, but in my scenario, the reason for this error is: Edittext is having focus, and this error occurs when edittext.getText() is used. To avoid this error you must:
edittext.gettext().toString(); Note: This edittext must have focus to make this error.

As mentioned here, this can happen because of the Android Advanced Profiling tool.

Disable it from the Run/Debug Configurations dialog:

It also happened to me because of Advanced Profiling option is enabled.

To disable the advanced profiling, follow these steps:

  1. Select Run > Edit Configurations.
  2. Select your app module in the left pane.
  3. Click the Profiling tab, and then uncheck Enable advanced profiling. Learn more

Assume the fragment or Activity have a non EditTextView named mTv; At some appropriate time,mTv.requestFocuse(); This works for me. Hope this helps you.

Make sure the input connection is not null in your onCreateInputConnection override method.

@Override
public InputConnection onCreateInputConnection(EditorInfo outAttrs) {
    InputConnection inputConnection = super.onCreateInputConnection(outAttrs);
    if (inputConnection == null)
    {
        return null;
    }
    return new MyInputConnectionWrapper(inputConnection,
            true);
}

Where MyInputConnectionWrapper is your custom input connection wrapper which is extended from InputConnectionWrapper.
