Android : Unable to start activity / Fail to connect to Camera service

I am trying to build an app which can turn on and off Camera Flash of my device . In Code its not showing any error but while launching the app on my device it's start to Crash .
Report bug is showing some Unable to start activity and something like Fail to connect Camera Services .
Since I am new in android Development and don't have enough knowledge.
I had already seen few questions regarding this but not able to find some useful information. All answers were approximately suggesting adding using permission in manifest file which I already did.
content of manifest file:
<?xml version="1.0" encoding="utf-8"?>

}
}
}
I have uploaded image of report bug of my mobile device

I'm posting the code to open the camera,please make changes as per your need.
try this:
static Camera camera = null;
and declare the following:
try{
if(clickOn == true) {
clickOn = false;
camera = Camera.open();
Parameters parameters = camera.getParameters();
parameters.setFlashMode(Parameters.FLASH_MODE_TORCH);
camera.setParameters(parameters);
camera.startPreview();
remoteViews.setViewVisibility(R.id.button1, View.GONE);
remoteViews.setViewVisibility(R.id.button2, View.VISIBLE);
localAppWidgetManager.updateAppWidget(componentName, remoteViews);
} else {
clickOn = true;
camera.stopPreview();
camera.release();
camera = null;
remoteViews.setViewVisibility(R.id.button1, View.VISIBLE);
remoteViews.setViewVisibility(R.id.button2, View.GONE);
localAppWidgetManager.updateAppWidget(componentName, remoteViews);
}
} catch(Exception e) {
Log.e("Error", ""+e);
}
After using camera, Don't forget to release it by following statement:
camera.release();
Also it may be the case that your app is not given permission to open camera at run time. Because from android 6.0 it is necessary to to have runtime permission to do specific tasks.
So if you are using Android 6.0(Marshmallow) or above, please check that the permission is enabled or not by following this:
The permission for camera could be disabled and should be enabled from the app settings. Settings -> Apps -> [Your App] -> Permissions.
That is what worked for me. Hope this help you too :)
EDIT
And please use e.printstacktrace() in your catch block to get error logcat.

i think there is problem while releasing the camera . Since you have written release method in onStop ,your camera will get release only when app is closed. try to release the camera when you are turning off the flash in button click method.

I got where i was wrong . Codes written above are Right . The only problem , i was using marshmallow in which we have to give permission to obtain camera permission through device .

AdColony - AdMob Mediation / Test Ads Worked but Live Ads Does Not Worked

I am a newbie in both in this forum and in Android world. I just developed a singleplayer trivia game, named "Reklamsız Bilgi Yarışması", only supports my local language but accessable in all over the world.
I just followed the guides and integrated AdColony to my AdMob account and get the perfect results, with test video ads.
However, after going live, nothing happened. Many of my customers wrote me that they can not get Ad Videos. Also, in admob, I saw 650 requests happened and only 4 of them get the video!
In AdColony statistics, I saw only 5 lucky guy requested the video and got watched full video, then took their rewards.
So, how could it be? Hundreds of request but only %0.25 of them were answered by AdMob (Or AdColony), I could not understand.
Lastly, %98 percent of my customers are from Turkey, %1 from Azerbaijan and %1 from Germany.
Is there any possible mistake in coding? Because I saw the test ads, on my physical device, not on the emulator also.
Thank You !

Here are all codes that I used, which are about the "Rewarded Video Ads"

I could not solve the problem but i think it is caused by AdColony. Because 7 people could manage to see live Ads, the others got the warning as "RewardedVideoFailedtoLoad". I think AdColony limited my Ad views because my App has only 2.500 hit now and also almost 99% exist in Turkey. Probably about the location and download numbers. I've just updated my game with Chartboost.

Could you please let me know what I am doing wrong and how can I solve this error?

From my experience there are 4 types of Android devices in regard BLE advertisement:
Devices with Android pre-5.0 - LE Advertisement not supported
Devices with Android 5+ that don't support LE Advertisement and return null from getBluetoothLeAdvertiser(). Those devices return false from isMultipleAdvertisementSupported(). They do this even with Bluetooth ON (see Note below).
Devices with Android 5+ that return the BluetoothLeAdvertiser object, but each try of advertising ends with ADVERTISE_FAILED_TOO_MANY_ADVERTISERS error (this is the case you have). Those devices return true from isMultipleAdvertisementSupported() which as you see is not true. So far I've seen only one phone from this category: Sony xperia z1 compact, but if there is one, there are more.
Devices with Android 5+ that support LE Advertisement. Those return true from isMultipleAdvertisementSupported() but ONLY when Bluetooth is ON.
Note: in the 2., 3. and 4. the BluetoothLeAdvertiser object is returned ONLY when Bluetooth is ON. Otherwise null is returned, so you actually have no clue whether the device supports LE Advertisement or not until Bluetooth is enabled.
Check the nRF Connect app: Disable Bluetooth, install the app, open and select Advertiser tab or Navigation menu -> Device information. It will ask you to turn Bluetooth ON before the status will be shown.

See this question for a possible answer, BLE Advertisments are not supported on every device.
Also try to omit the device name as suggested here.

You only need to add this code: #TargetApi(Build.VERSION_CODES.M) over your method

I am trying to run this sample program to try to get familiar with the Speech Recognizer software..
Could this be an issue being caused by the fact that I'm running it on android studio rather than a real device? I am pretty stuck on this.

In case anyone comes to this question and none of the other answers help, you might want to try requesting permissions using the following code:
private void requestRecordAudioPermission() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
String requiredPermission = Manifest.permission.RECORD_AUDIO;
// If the user previously denied this permission then show a message explaining why
// this permission is needed
if (checkCallingOrSelfPermission(requiredPermission) == PackageManager.PERMISSION_DENIED) {
requestPermissions(new String[]{requiredPermission}, 101);
}
}
}

Error 9 ERROR_INSUFFICIENT_PERMISSIONS is also thrown when google does not have record_audio permission.
Check the Settings -> Apps -> Google -> Permissions -> Microphone

It was just a problem with it not being supported on emulators. It works on a physical device.

What I found is that if you are "just a physical device" and you still get the same error, that is most probably is because if the target SDK in the gradle file. you see in later versions they have changed the level of permission to dangers, so by downgrading it, then you it will work.
"I am not an expert in this, but this worked from me fine"

try these links for references to your project also check all android manifest permissions here and here is a sample project
hope these hints help to solve your problem!

onIBeaconServiceConnect() is not getting called in android

I am using AndroidIbeacon library released by radiusnetworks and I am able to run their demo app successfully. But when I add that to my application onIBeaconServiceConnect() method is not called.

Kindly help me to solve this issue. thanks

If manifest merging does not work, try this (worked for me):
Add the following service declarations to your AnroidManifest.xml, replacing {my app's package name} with the fully qualified package name of your Android application.
<service android:enabled="true"
android:exported="true"
android:isolatedProcess="false"
android:label="iBeacon"
android:name="com.radiusnetworks.ibeacon.service.IBeaconService">
</service>
<service android:enabled="true"
android:name="com.radiusnetworks.ibeacon.IBeaconIntentProcessor">
<meta-data android:name="background" android:value="true" />
<intent-filter
android:priority="1" >
<action android:name="{my app's package name}.DID_RANGING" />
<action android:name="{my app's package name}.DID_MONITORING" />
</intent-filter>
</service>

The most common cause of this issue is that the proper entries to start the library's service are not in the project AndroudManifest.xml file. Your new project must pull in these entries from the library's manifest using a feature called manifest merging.
Make sure you have followed the setup instructions here. If using Eclipse, verify your project.properties has manifestmerger.enabled=true.

adding
manifestmerger.enabled=true
in project.properties worked for me!
