在我保存后拍摄相机图像然后不在activity
并且崩溃应用程序返回但是在我的三星手机中一切正常但在redmi手机和其他手机中出现此错误
at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:635)
Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String android.net.Uri.toString()' on a null object reference

at android.app.Activity.dispatchActivityResult(Activity.java:6562)
at android.app.ActivityThread.deliverResults(ActivityThread.java:3768)
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST_CODE && resultCode==RESULT_OK)
{
Uri uri = data.getData();
Log.e("Image : ", uri.toString());
Intent intent = new Intent(this, PictureActivity.class);
intent.putExtra("imgUrl", uri.toString());
startActivity(intent);
}
}
这是我有意图的第二项活动
Bundle bundle = getIntent().getExtras();
if (bundle != null) {
Log.e("ashish", bundle.getString("imgUrl") + "");
path = Uri.parse(bundle.getString("imgUrl"));
}
ImageView selfiiii = (ImageView) findViewById(R.id.mySelfie);
selfiiii.setImageURI(path);
答案 0 :(得分:0)
试试这个
相机意图:
private void dispatchTakePictureIntent() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// Ensure that there's a camera activity to handle the intent
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException ex) {
// Error occurred while creating the File
}
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = FileProvider.getUriForFile(this,
"com.example.android.fileprovider",
photoFile);
mTempCameraPhotoFile = photoFile;
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, PHOTO_REQUEST);
}
}
}
在存储中保存图像文件:
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = image.getAbsolutePath();
return image;
}
在onActivityResult:
if (requestCode == PHOTO_REQUEST && resultCode == RESULT_OK) {
try {
String filePath = mTempCameraPhotoFile.getPath();
Uri uri = Uri.fromFile(mTempCameraPhotoFile);
Bitmap bitmap = null;
bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), uri);
} catch (IOException e) {
e.printStackTrace();
}
}
