从相机捕获照片时获取IllegalArgumentException [英] Getting IllegalArgumentException while capturing photo from Camera
本文介绍了从相机捕获照片时获取IllegalArgumentException的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
在我的项目中，我正在使用FileProvider.getUriForFile和给定的 provider_paths.xml 文件:
In my project I am using FileProvider.getUriForFile with given provider_paths.xml file:
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-files-path name="StrengGeheim" path="/" />
</paths>
我在
This I added in my AndroidManifest.xml inside tag:
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths"/>
</provider>
这是我的相机意图代码:
This is my camera Intent code:
private void cameraIntent() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri();
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult(intent, CAMERA);
}
private Uri getOutputMediaFileUri() {
try {
return FileProvider.getUriForFile(getContext(), BuildConfig.APPLICATION_ID + ".provider",getOutputMediaFile());
}
catch (IOException ex){
ex.printStackTrace();
Toast.makeText(getContext(), MESSAGE_FAILED, Toast.LENGTH_SHORT).show();
}
return null;
}
在文件Uri中，路径类似于/storage/emulated/0/StrengGeheim/06673da7-876f-4a53-9a3d-288ae033f7ac ，并且从图库存储图像的路径也相同.但是在捕获照片和应用程序关闭时，我仍然遇到错误.
In file Uri the path is something like this /storage/emulated/0/StrengGeheim/06673da7-876f-4a53-9a3d-288ae033f7ac and the path of storing image from gallery is also same. But still I am getting below error while capturing photo and app is closing.

这是我处理OnActivityResult的方式:
This is how I am handling OnActivityResult:
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == getActivity().RESULT_CANCELED) {
return;
}
try {
if (requestCode == GALLERY && data != null) {
Bitmap bitmap = getBitmapFromData(data, getContext());
File mediaFile = getOutputMediaFile();
String path = saveImage(bitmap, mediaFile);
Log.println(Log.INFO, "Message", path);
Toast.makeText(getContext(), MESSAGE_IMAGE_SAVED, Toast.LENGTH_SHORT).show();
loadImage.setImageBitmap(bitmap);
imageTextMessage.setVisibility(View.INVISIBLE);
} else if (requestCode == CAMERA) {
File file = new File(fileUri.getPath());
final Bitmap bitmap = BitmapFactory.decodeFile(fileUri.getPath());
loadImage.setImageBitmap(bitmap);
saveImage(bitmap, file);
Toast.makeText(getContext(), MESSAGE_IMAGE_SAVED, Toast.LENGTH_SHORT).show();
imageTextMessage.setVisibility(View.INVISIBLE);
}
} catch (Exception ex) {
ex.printStackTrace();
Toast.makeText(getContext(), MESSAGE_FAILED, Toast.LENGTH_SHORT).show();
}
}
private Bitmap getBitmapFromData(Intent intent, Context context){
Uri selectedImage = intent.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = context.getContentResolver().query(selectedImage,filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
return BitmapFactory.decodeFile(picturePath);
}
private String saveImage(Bitmap bmpImage, File mediaFile) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
bmpImage.compress(Bitmap.CompressFormat.PNG, 100, bytes);
try {
FileOutputStream fo = new FileOutputStream(mediaFile);
fo.write(bytes.toByteArray());
MediaScannerConnection.scanFile(getContext(),
new String[]{mediaFile.getPath()},
new String[]{"image/png"}, null);
fo.close();
return mediaFile.getAbsolutePath();
} catch (IOException ex) {
ex.printStackTrace();
}
return "";
}
请问有人可以帮忙吗?
推荐答案
<paths>
<external-files-path name="StrengGeheim" path="/" />
</paths>
此配置适用于存储在getExternalFilesDir()下的文件.根据您的错误，那不是您的文件存储的位置.将此更改为:
This configuration is for files stored under getExternalFilesDir(). That is not where your files are stored, based on your error. Change this to:
<paths>
<external-path name="StrengGeheim" path="."/>
</paths>
