[英]Android ACTION_IMAGE_CAPTURE sometimes not calling onActivityResult
In our code we are using getPhoto method that looks like this: 在我们的代码中,我们使用的getPhoto方法如下所示:
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);
}
And onActivityResult: 和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);
}
}
}
}
Sometimes, when I'm pressing 'Ok', onActivityResult
is not called ( Came
not wrote). 有时,当我按'Ok'时, onActivityResult
不被调用( Came
not written)。 What is wrong in my code? 我的代码有什么问题?
EDIT: 12-04 12:43:36.040: INFO/WindowManager(145): WIN DEATH: Window{40839990 com.skalar/com.skalar.activities.RegisterActivity paused=false}
appears in code when onActivityResult
not called. 编辑: 12-04 12:43:36.040: INFO/WindowManager(145): WIN DEATH: Window{40839990 com.skalar/com.skalar.activities.RegisterActivity paused=false}
当未调用onActivityResult
时, 12-04 12:43:36.040: INFO/WindowManager(145): WIN DEATH: Window{40839990 com.skalar/com.skalar.activities.RegisterActivity paused=false}
出现在代码中。
Is it possible that your activity is getting killed and that is the reason on onActivityResult is not getting executed? 你的活动是否有可能被杀死,这就是onActivityResult未被执行的原因? When the camera Intent returns, normally onActivityResult followed by onResume will be executed. 当相机Intent返回时,通常会执行onActivityResult后跟onResume。 Put a log statement in your onPause and onResume methods and check the sequence of execution. 在onPause和onResume方法中放入一个日志语句,并检查执行顺序。
I faced same problem , once check have you put any tag related to History ?
Do not put android:noHistory="true" tag in manifest if you use android:noHistory="true" in your activity inside manifest , it will remove from stack after on stop . 如果您在清单中的活动中使用android:noHistory =“true”,请不要在清单中放置android:noHistory =“true”标记,它会在停止后从堆栈中删除。
Note : if you are using tab activity then also you should not use android:noHistory="true" or else simply put android:noHistory="false" in activity inside manifest . 注意:如果你正在使用tab活动,那么你也不应该使用android:noHistory =“true”,否则只需将android:noHistory =“false”放入manifest中的活动中。
may be my explanation is wrong but I got solution . 可能是我的解释是错的,但我得到了解决方案。

The method that takes care of the capture only returns correctly
(using the finnish() method, I think) if the picture can be saved
correctly in the file specified by that URI. If there's an exception
(such as an IO exception) it will be captured and nothing will be
done, so you'll never know. I believe that 'myTestFile' is a file that
can only be read/written within your own application and that's why
image_capture can't write to it.
So the problem is 所以问题是
captureFile = new File(getCaptureFilePath());
intent.putExtra(MediaStore.EXTRA_OUTPUT, captureUri);
you can solve the problem by setting captureFile the returned value of this method: 你可以通过设置captureFile这个方法的返回值来解决问题:
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File directory = new File(Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES), "your subdirectory for Picture directory");
if(!directory.exists() && !directory.mkdir())
return null;
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
directory /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
return image;
}
