ActivityManagerプロセスが終了しました

Question

私のアプリには5つの画面が含まれています。最初の画面では、サーバーからデータを読み込み、2番目の画面でリストビューに表示します。リストビューでは、各行の画像を表示する必要があります。これらのイメージは動的にダウンロードされ、キャッシュされています。ダウンロードはバックグラウンドで行われ、私はリストビューのためにnotifyDataSetChanged（）を与えました。

ダウンロードが進行中の場合は、他の3つの画面に移動できます。これらの3つの画面では、同じ機能を実行するボタンがあります。つまり、第2の画面と同じリストを含むダイアログを表示します。

問題は、このダイアログボックスから2〜3回などの値を選択すると、現在のアクティビティが消えて自動的に2ページ目に移動します。

私はそれの背後にある理由を特定することができません。私が得るログを見てください。誰もこの問題が起こっている理由を教えてもらえますか？

Answer 1

スタックトレースの最初の奇妙なテキストの多くは、ネイティブクラッシュダンプです。クラッシュは、ネイティブライブラリの1つで未処理のランタイムエラーが発生したために発生します。

08から25：10：44：31.635：INFO/DEBUG（16421）：信号11（SIGSEGV）、コード1（SEGV_MAPERR）、故障ADDRのdeadbaad

エラーは、非マップアドレス 0xdeadbaadへのアクセスが起こります

このエラーが発生すると、アプリケーションプロセスは終了し、再起動されます。 SecondScreenActivityが作成され、その状態が最後に保存された状態から復元されます。

EDIT：問題はあなたのコード内にあるとは思わない。それはAndroidのバグだと思う。 バグレポート：http://code.google.com/p/android/issues/detail?id=14498です。複数のスレッドから

APKが使用しているビットマップ、（それがされている間または）それ がされた後、それを再利用するリサイクル：

このレポートには、次の結論が含まれています。 Skiaグラフィックスライブラリ は完全にスレッドセーフではなく、 同期を追加するには高価すぎるため、 プラットフォームでは修正されません。

だから、あなたはrecycle()に注意する必要があります。

Answer 2

このコードをお試しください。

まず、すべての変数/オブジェクトをグローバルに宣言します。

次に、SDCardのダウンロードイメージの機能を使用します。

最初にImageViewのこのImageをダウンロードボタンのClickイベントで次のように呼び出します。コールの後

Bitmap bmpImage; 
bmpImage = loadBitmapFromView(imgview1); 
downloadImageinphone(bmpImage); 



public static Bitmap loadBitmapFromView(ImageView v) { 
     Bitmap b = Bitmap.createBitmap(v.getWidth(), v.getHeight(), 
       Bitmap.Config.ARGB_8888); 
     Canvas c = new Canvas(b); 
     // v.layout(0, 0, v.getWidth(), v.getHeight()); 
     v.draw(c); 
     return b; 
} 

この機能： -

Uri uri; 
Bitmap b; 

    private void downloadImageinphone(Bitmap b) { 
     String filename = "tempImage"; 
     ContentValues values = new ContentValues(); 
     values.put(Images.Media.TITLE, filename); 
     values.put(Images.Media.DATE_ADDED, System.currentTimeMillis()); 
     values.put(Images.Media.MIME_TYPE, "image/png"); 
     uri = getContentResolver().insert(Images.Media.EXTERNAL_CONTENT_URI, 
       values); 

     try { 
      OutputStream outStream = getContentResolver().openOutputStream(uri); 
      // outStream = new FileOutputStream(file); 
      b.compress(Bitmap.CompressFormat.PNG, 100, outStream); 
      outStream.flush(); 
      outStream.close(); 
      Log.d("done", "done"); 
      Toast.makeText(MainActivity.this, 
        "Photo is Successfully Downloaded", 
        Toast.LENGTH_LONG).show(); 
     } catch (FileNotFoundException e) { 
      e.printStackTrace(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
     b.recycle(); 
    }
