CRASH:

Как ваш StackTrace говорит:

"java.lang.OutOfMemoryError: Failed to allocate a 15052812 byte allocation with 12653776 free bytes and 12MB until OOM"

вы пытаетесь отобразить огромный растровое изображение на ваш взгляд. Вашему телефону это не нравится.

Два решения:

• уменьшить размеры вашего изображения, использовать меньшее изображение ... и повторов!
• или установите android:largeHeap="true" в вашем манифесте, в вашем приложении теги. Это увеличит размер вашей кучи и позволит избежать ошибки, но ваше приложение, вероятно, будет отставать.
