[英]How to get the URI from a camera intent?
I have already read this post: Get uri from camera intent in android but it didn't help me. 我已经读过这篇文章: 从android中的相机意图中获取uri,但这并没有帮助我。
To handle the camera request I've used this code: 为了处理相机请求,我使用了以下代码:
public void startCamera() {
if (PermissionUtils.requestPermission(
this,
CAMERA_PERMISSIONS_REQUEST,
Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.CAMERA)) {
//Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
Uri photoUri = FileProvider.getUriForFile(this, getApplicationContext().getPackageName() + ".provider", getCameraFile());
intent.putExtra(MediaStore.EXTRA_OUTPUT, photoUri);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivityForResult(intent, CAMERA_IMAGE_REQUEST);
}
}
public File getCameraFile() {
File dir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
return new File(dir, FILE_NAME);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_IMAGE_REQUEST && resultCode == RESULT_OK) {
Uri photoUri = FileProvider.getUriForFile(this, getApplicationContext().getPackageName() + ".provider", getCameraFile());
uploadImage(photoUri);
}
}
When I call the function "startCamera" the app crashes giving me error at the line: 当我调用函数“ startCamera”时,应用程序崩溃,并在行处给我错误:
Uri photoUri = FileProvider.getUriForFile(this, getApplicationContext().getPackageName() + ".provider", getCameraFile());"
Any help? 有什么帮助吗? Thank you!
谢谢!
FIXED by adding to the "AndroidManifest" this: 通过在“ AndroidManifest”中添加以下内容进行修复 :
<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>
