I'm trying to access the camera on my phone. I'm writing a simple stub app prior to putting the code in a widget. I'm not getting very far. The code always throws a runtime exception "failed to connect to camera service" The code(pinched from a commonsware example) which goes wrong is:
@Override
public void onResume() {
super.onResume();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.GINGERBREAD) {
Camera.CameraInfo info = new Camera.CameraInfo();
for (int i = 0; i < Camera.getNumberOfCameras(); i++) {
Camera.getCameraInfo(i, info);
if (info.facing == Camera.CameraInfo.CAMERA_FACING_BACK) {
try {
// Gets to here OK
camera = Camera.open(i);
} catch (Exception e) {
e.printStackTrace();
// throws runtime exception :"Failed to connect to camera service"
}
}
}
}
}
and my manifest is (corrected 20th Oct):
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.nbt.cameratest"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="9" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:label="@string/app_name"
android:name=".CameraTestActivity" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
</application>
</manifest>
Can anyone please suggest what might be wrong?
UPDATE 20th Oct
Logcat in SDK 4.0 is broken and wont show the end of the log, so I've cut this bit as best as I can from command line adb logcat:
W/ServiceManager( 2588): Permission failure: android.permission.CAMERA from uid=10136 pid=5744
E/CameraService( 2588): Permission Denial: can't use the camera pid=5744, uid=10136
W/System.err( 5744): java.lang.RuntimeException: Fail to connect to camera service
W/System.err( 5744): at android.hardware.Camera.native_setup(Native Method)
W/System.err( 5744): at android.hardware.Camera.<init>(Camera.java:294)
W/System.err( 5744): at android.hardware.Camera.open(Camera.java:255)
etc..
I don't know why I haven't permission as it is declared in the manifest
This question is related to
android
I had the same issue. Tried all the solutions mentioned here but nothing worked. So i rebooted my device and suddenly the issue solved.
The problem is related to permission. Copy following code into onCreate() method. The issue will get solved.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (checkSelfPermission(Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
requestPermissions(new String[] {Manifest.permission.CAMERA}, 1);
}
}
After that wait for the user action and handle his decision.
@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
switch (requestCode) {
case CAMERA_PERMISSION_REQUEST_CODE:
// If request is cancelled, the result arrays are empty.
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
//Start your camera handling here
} else {
AppUtils.showUserMessage("You declined to allow the app to access your camera", this);
}
}
}
since this question was asked 4 years back..and i didn't realised that unless mentioned by the Questioner..when there were no Run time permissions support.
but hoping it useful for the users who still caught in this situation.. Have a look at Run Time Permissions ,for me it solved the problem when i added Run time permissions to grant camera access. Alternatively you can grant permissions to the app manually by going to your mobile settings=>Apps=>(select your app)=>Permissions section in the appeared window and enable/disable desired permissions. hope this will work.
running your code hundred times may affect the camera to function wrongly.Your activity may be performing correctly but system could not buy it.so camera forces stop. One main tip all missed is rebooting your phone and not only eclipse..It worked for me..
For newer android versions that support setting permissions per app (since Marshmallow, 6.0) the permission for camera could be disabled and should be enabled from the app settings.
when you use camera.open; and you finish using the camera write this commend camera.release(); this will stop the camera so you can use it again
I know this question has been answered long time ago, but I would like to add a small thing.
To everyone having the same error, make sure to add this permission in you manifest file:
<uses-permission android:name="android.permission.CAMERA" />
IMPORTANT to use the CAPITAL letters for CAMERA, as I had the permission with small letters and it didn't work.
Make sure to call the release() method to release the camera when it is no longer needed, or you will not be able to use the camera. Perhaps as a sanity check, see if your regular camera works. If it says it fails, then your previous attempts at runni
I came up with the same problem and I'm sharing how I fixed it. It may help some people.
First, check your Android version. If it is running on Android 6.0 and higher (API level 23+), then you need to :
**<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />**
<application ...>
...
</application>
Then, request that the user approve each permission at runtime
if (ContextCompat.checkSelfPermission(thisActivity, Manifest.permission.CAMERA)
!= PackageManager.PERMISSION_GRANTED) {
// here, Permission is not granted
ActivityCompat.requestPermissions(this, new String[] {android.Manifest.permission.CAMERA}, 50);
}
For more information, have a look at the API documentation here
