同じアプリケーションを Android Studio から別のデバイスにインストールすると、すべてのデバイスに正常にインストールされますが、一部のデバイスでこのアプリ内の内部ストレージのファイルを操作すると、起動後に次のエラーが発生します。

同時に、この例外なく、同じアプリケーションが異なるデバイスで動作します。ルートデバイスで確認しましたが、この例外が発生した場合でも、zip ファイルがdata/data/packagename/filesフォルダーに存在します。例外が発生するコードは次のとおりです ( の行fileStream.available())。
RequestBody requestBody = new RequestBody() {
@Override
public MediaType contentType() {
return MediaType.parse(file.getMimeType());
}
@Override
public long contentLength() throws IOException {
return fileStream.available();
}
@Override
public void writeTo(BufferedSink sink) throws IOException {
Source source = null;
try {
source = Okio.source(fileStream);
sink.writeAll(source);
} finally {
Util.closeQuietly(source);
}
}
};
RequestBodyokhttp3 ライブラリの抽象クラスはどこにありますか。このエラーの理由は何ですか?
PS私はまた、他のコンピューターに構築されたこのアプリケーションのapkをインストールしようとしました（私のコンピューターにadbを使用してインストールしました）。これらのファイルの動作に大きな変更はなく、同じデバイスで例外なく実行されますこの例外が以前に発生した場所...だから、さらに混乱します...
PSSそして、実行gradlewボタンではなくターミナルとタスクを使用して Android Studio で同じアプリケーションを構築している場合、このアプリケーションはこのエラーなしで動作します。私のAndroid Studioに何かあるようですが、正確には想像もできず、びっくりしました...
