Android 上的异步任务冻结

我的活动有奇怪的问题，我不知道该怎么办...

private Bitmap mBitmap;

@Override
public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    mBitmap = initBitmap();
}


@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.menuItemNew:
            doSomething();
            return true;    
        case R.id.menuItemNative:
            showList();
            return true;

    }

    return(super.onOptionsItemSelected(item));
}

private boolean selected;

private void showList() {
    CharSequence[] items = {"First", "Second"};

    selected = false;
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Selection mode");
    builder.setSingleChoiceItems(items, 0, new OnClickListener() {

        public void onClick(DialogInterface dialog, int item) {
            selected = item == 1;
        }
    });
    builder.setPositiveButton("OK", new OnClickListener() {

        public void onClick(DialogInterface dialog, int which) {
            if (selected) {
                new NativeTask().execute();
            }
        }
    });
    Dialog dia = builder.create();
    dia.show();

}

private class NativeTask extends AsyncTask<String, String, String> {

    @Override
    protected String doInBackground(String... params) {
        Log.i("task", "before Native Call");
        int buffer[] = new int[mBitmap.getWidth() * mBitmap.getHeight()];
        mBitmap.getPixels(buffer, 0, mBitmap.getWidth(), 0, 0, mBitmap.getWidth(), mBitmap.getHeight());
        int[] result = NativeLibrary.process(pixels);
        Log.i("task", "after Native Call");

        return null;
    }

    @Override
    protected void onProgressUpdate(String... progress) {
        Log.i("task", "in progress");
    }

    @Override
    protected void onPostExecute(String a) {

        Log.i("task", "in postExecute");
    }
}

这是我的活动的相关部分。如您所见，我在那里有菜单，如果您单击第二个项目，则会出现包含两个项目列表的对话框。然后，如果您选择并确认列表中的第二项，则将执行 AsyncTask 并调用本机代码中的某些方法。

看起来不错（对我来说），但存在一些问题 - 当我从列表中选择第二项时，本机方法被正确调用......但活动冻结了。

日志包含所有三个消息：

  • 任务：本机调用之前
  • 任务：本机调用之后
  • 任务：在 postExecute

我不知道还需要做什么。我错过了什么吗？为什么当我使用 AsyncTask 时我的 Activity 冻结？我在 AsyncTask 中使用位图有问题吗？ NativeLibrary.process(int[]) 返回正确的数组，没有问题......那么为什么？

我会很高兴收到任何提示！

PS：我很抱歉我的英语不好

编辑：这是冻结的日志

在第二种情况下它没有释放但活动崩溃了...

编辑：我在本机部分发现了奇怪的内存泄漏，当我修复它时，一切都好:)

原文

I have weird problem with my Activity and I dont know what to do...

private Bitmap mBitmap;

@Override
public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    mBitmap = initBitmap();
}


@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.menuItemNew:
            doSomething();
            return true;    
        case R.id.menuItemNative:
            showList();
            return true;

    }

    return(super.onOptionsItemSelected(item));
}

private boolean selected;

private void showList() {
    CharSequence[] items = {"First", "Second"};

    selected = false;
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Selection mode");
    builder.setSingleChoiceItems(items, 0, new OnClickListener() {

        public void onClick(DialogInterface dialog, int item) {
            selected = item == 1;
        }
    });
    builder.setPositiveButton("OK", new OnClickListener() {

        public void onClick(DialogInterface dialog, int which) {
            if (selected) {
                new NativeTask().execute();
            }
        }
    });
    Dialog dia = builder.create();
    dia.show();

}

private class NativeTask extends AsyncTask<String, String, String> {

    @Override
    protected String doInBackground(String... params) {
        Log.i("task", "before Native Call");
        int buffer[] = new int[mBitmap.getWidth() * mBitmap.getHeight()];
        mBitmap.getPixels(buffer, 0, mBitmap.getWidth(), 0, 0, mBitmap.getWidth(), mBitmap.getHeight());
        int[] result = NativeLibrary.process(pixels);
        Log.i("task", "after Native Call");

        return null;
    }

    @Override
    protected void onProgressUpdate(String... progress) {
        Log.i("task", "in progress");
    }

    @Override
    protected void onPostExecute(String a) {

        Log.i("task", "in postExecute");
    }
}

This is relevant part of my Activity. As you see, I have menu there and if you click on second item, dialog with list of 2 items appears. Then if you select and confirm second item in list, AsyncTask is being executed and some method from native code is called.

Looks good (for me), but some problem is there - when I select second item from list, native method is correctly called... but Activity freezes.

Log contains all three messages:

  • task: before Native call
  • task: after Native call
  • task: in postExecute

I don't know what more I have to do. Am I missing something? Why is my Activity freezing when I use AsyncTask? Is problem I'm working with Bitmap inside AsyncTask?
NativeLibrary.process(int[]) return correct array, no problem there.... so WHY?

I will be happy for any tip!

P.S: I'm sorry for my bad english

EDIT: Here's log for freeze

我很困惑，因为 NativeTask 的声明声明它需要 String 类型的参数，如下所示：

new NativeTask().execute(string1);

不是

new NativeTask().execute();

，您似乎也没有在 doInBackground 中使用字符串参数：

String inString= params[0];

希望有帮助，

I am confused as the declaration of NativeTask declares that it takes a Parameter(s) of type String as in:

new NativeTask().execute(string1);

not

new NativeTask().execute();

also you do not seem to use the string parameter in doInBackground as:

String inString= params[0];

Hope that helps,
JAL

我发现本机部分存在一些内存泄漏。当我修复它时，一切正常。

I found some memory leak in native part. When I fixed it, everything works correct.
