Android的ACTION_IM​​AGE_CAPTURE有时不叫onActivityResult [英] Android ACTION_IMAGE_CAPTURE sometimes not calling onActivityResult

问题描述

在我们的code，我们使用的是getPhoto方法是这样的：

In our code we are using getPhoto method that looks like this:

public void getPhoto(View view) {
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

    captureFile = new File(getCaptureFilePath());
    captureUri = Uri.fromFile(captureFile);
    intent.putExtra(MediaStore.EXTRA_OUTPUT, captureUri);

    startActivityForResult(intent, CAPTURE_IMAGE);
}

和onActivityResult：

And onActivityResult:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    Log.w(TAG, "Came");

    if (resultCode == RESULT_OK) {
        if (requestCode == CAPTURE_IMAGE) {
            try {
                captureFile = new File(getCaptureFilePath());
                captureUri = Uri.fromFile(captureFile);

                Bitmap scaledBitmap = decodeFileAndResize(captureFile);
                saveResizedAndCompressedBitmap(scaledBitmap);

                Bitmap rotatedBitmap = convertToRotatedBitmap(scaledBitmap);
                driverPhoto.setImageBitmap(rotatedBitmap);

                Log.w(TAG, "Before recycle");

                if (rotatedBitmap != scaledBitmap) {
                    scaledBitmap.recycle();
                    scaledBitmap = null;
                    System.gc();
                }

                Log.w(TAG, "After recycle");
            } catch (IOException e) {
                BugSenseHandler.log(TAG, e);
            }
        }
    }
}

有时候，当我pressing'确定'， onActivityResult 不叫（来到不写）。什么是错误的，我code？

Sometimes, when I'm pressing 'Ok', onActivityResult is not called (Came not wrote). What is wrong in my code?

推荐答案

难道你的活动是被杀，并没有得到执行，关于onActivityResult的原因是什么？当摄像机意图的回报，通常onActivityResult随后onResume将被执行。把日志语句进行的onPause和onResume方法，并检查执行顺序。

Is it possible that your activity is getting killed and that is the reason on onActivityResult is not getting executed? When the camera Intent returns, normally onActivityResult followed by onResume will be executed. Put a log statement in your onPause and onResume methods and check the sequence of execution.
