ActivityManager进程已死问题

android
6
我的应用程序包含5个屏幕。在第一个屏幕中，我从服务器加载一些数据，并在第二个屏幕的listview中显示这些数据。在listview中，我需要为每一行显示一张图片。这些图像是动态下载并被缓存的。下载发生在后台，我已经为listview给出了notifyDataSetChanged()。
当下载正在进行时，我可以进入其他3个屏幕。在这3个屏幕中，我有一个按钮执行相同的功能，即显示一个对话框，其中包含与第二屏幕相同的列表。
问题是，当我从此对话框中选择一个值（比如2或3次），当前活动就会消失，自动切换到我的第二页面。
我无法确定其原因。请查看我得到的日志。有人能告诉我为什么会发生这个问题吗？

你好，马修，你是否将图像存储/下载到SD卡中？ - Dipak Keshariya
图像的分辨率是什么？例如，128128、7272。 - Dipak Keshariya
请提供下载图像代码函数。 - Dipak Keshariya
请提供一些代码以便我可以将您的代码与我的代码进行比较，然后给您答案。 - Dipak Keshariya

堆栈跟踪开头的大量奇怪文本是原生崩溃转储。崩溃发生是因为一个本地库中未处理的运行时错误。该错误发生是因为访问了未映射的地址0xdeadbaad：

08-25 10:44:31.635: INFO/DEBUG(16421): signal 11 (SIGSEGV)，code 1 (SEGV_MAPERR)，fault addr deadbaad

此错误发生后，应用程序进程将被终止并重新启动。创建SecondScreenActivity，然后从上次保存的状态恢复它的状态。 编辑：我认为问题不在您的代码中。似乎这是Android的一个bug。以下是一个错误报告：http://code.google.com/p/android/issues/detail?id=14498。
此报告包含以下结论：

APK正在使用来自多个线程的位图，在回收之后（或在回收期间）重复使用它。 Skia图形库不完全支持多线程，并且引入附加同步代价太高，因此平台不会修复此问题。

所以您需要小心使用recycle()。

尝试这段代码。

首先在全局声明所有变量/对象。

然后使用以下函数在SD卡中下载图像。

首先在ImageView中显示此图像，在下载按钮的单击事件中调用以下函数。

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;
}

调用此函数后：-
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();
    }
