Answer 1

あなたの問題はここにあります：

java.lang.OutOfMemoryError: bitmap size exceeds VM budget

大きな画像を読み込んでいるようです。これには複数のオプションがあります: 1. BitmapOptions を使用してサイズを取得し、スケールを計算してから、必要なスケールでのみデコードします。

1. デバイスのニーズに合わせて、PC で直接画像のサイズを変更します。

このトピックの必読ページは次のとおりです: Android 開発者

PS。ここで重要なことは、UI スレッドで画像をデコードしてはならないということです。これは、アプリのパフォーマンスに影響します。

Answer 2

サイズが大きすぎるビットマップを読み込んでいます。Caused by: java.lang.OutOfMemoryError: bitmap size exceeds VM budget. ただし、解決策はあります。ビットマップをより低い解像度にデコードする必要があります[方法]。
