Add a file file_paths.xml to the resources directory res/xml/ in order to grant access to the correct folders:
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path
name="external_files"
path="."/>
</paths>
In your AndroidManifest.xml add the following:
<manifest ... >
<uses-feature android:name="android.hardware.camera"
android:required="true" />
...
<application>
...
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.pixplicity.example.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths" />
</provider>
</application>
</manifest>
Then launch the camera like so:
private void launchCamera() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// Check which app can handle taking pictures
ComponentName component = intent.resolveActivity(context.getPackageManager());
if (component != null) {
File output = createImageFile(context);
Uri uri = FileProvider.getUriForFile(
context,
BuildConfig.PROVIDER_AUTHORITY,
output);
intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
context.grantUriPermission(
component.getPackageName(),
uri,
Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
context.startActivityForResult(intent, REQUEST_CAMERA);
}
}
private File createImageFile(Context context) {
File dir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM), "Camera");
return File.createTempFile(
"IMG_" + System.currentTimeMillis() + ".jpg",
dir);
}
In this case the provider authority is com.pixplicity.example.fileprovider, which is specified in the manifest and in the build.gradle:
buildConfigField "String", "PROVIDER_AUTHORITY", "\"com.pixplicity.example.fileprovider\""
