我将我的nexus 5
Android操作系统版本更新为5.1.1,并更新了Google相机和Google相册应用程序.在此之后,当我尝试捕获图像并裁剪它时,我的应用程序崩溃并出现以下错误：

以前它工作正常.我使用的代码如下：
图像捕获代码：
try {
Intent imageCapture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (imageCapture.resolveActivity(getContext().getPackageManager()) != null) {
imageCapture.putExtra(MediaStore.EXTRA_OUTPUT,Uri.fromFile(new File(Environment.getExternalStorageDirectory().getAbsolutePath() + Constants.image_path)));
startActivityForResult(imageCapture,Constants.CAMERA_IMAGE_CAPTURE);
}
} catch (ActivityNotFoundException anfe) {
Toast.makeText(getContext(),"device doesn't support capturing images!",Toast.LENGTH_SHORT).show();
}
图像裁剪代码
@Override
protected void onActivityResult(int requestCode,int resultCode,Intent intent) {
super.onActivityResult(requestCode,resultCode,intent);
if (resultCode == RESULT_OK) {
if (requestCode == CAMERA_IAMGE_CROP) {
Bundle extras = intent.getExtras();//intent.getExtras() is always returns NULL here
Bitmap thePic = extras.getParcelable("data");
//setImageOnImageView(thePic);
} else if (requestCode == Constants.CAMERA_IMAGE_CAPTURE)) {
processCapturedImage();
}
}
}
private void processCapturedImage() {
try {
String path = Environment.getExternalStorageDirectory().getAbsolutePath() + Constants.image_path;
File file = new File(path);
if (file.exists()) {
BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.RGB_565;
Bitmap bm = BitmapFactory.decodeFile(path,options);
int rotate = AndroidUtils.getRotateValue(file.getAbsolutePath());
if (rotate != 0) {
Debug.print("Profile pic rotation value is not 0.");
/****** Image rotation ****/
Matrix matrix = new Matrix();
matrix.postRotate(rotate);
bm = Bitmap.createBitmap(bm,bm.getWidth(),bm.getHeight(),matrix,true);
}
picUri = getImageUri(getApplicationContext(),bm);
performCropAction();
} else {
Tools.showToast(EditProfileActivity.this,"Error occurred,please try again.");
}
} catch (Exception e) {
Debug.printException(e);
}
}
private void performCropAction() {
try {
Intent cropAction = new Intent("com.android.camera.action.CROP");
cropAction.setDataAndType(picUri,"image/*");
cropAction.putExtra("crop","true");
cropAction.putExtra("aspectX",1);
cropAction.putExtra("aspectY",1);
cropAction.putExtra("outputX",AS.getInPixels(100));
cropAction.putExtra("outputY",AS.getInPixels(100));
cropAction.putExtra("return-data",true);
startActivityForResult(cropAction,CAMERA_IAMGE_CROP);
}
catch (ActivityNotFoundException anfe) {
Toast.makeText(this,"your device doesn't support the crop action!",Toast.LENGTH_SHORT).show();
}
}
如你看到的,
Bundle extras = intent.getExtras();
这里的intent.getExtras()始终返回NULL.
任何帮助真的很感激！
谢谢.
解决方法
以上android 5.0裁剪功能在onActivityResult中返回URI,因此请相应地使用手机版本处理它.
Bitmap selectedBitmap;
if(Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
Bundle extras = data.getExtras();
selectedBitmap = extras.getParcelable("data");
}
else{
Uri uri = data.getData();
selectedBitmap=MediaStore.Images.Media.getBitmap(this.getContentResolver(),uri);
}
希望这可以帮助！
