I add bluetooth to my app but am running into the following problem. When I do the code:
mDiscoverBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if(!mBlueAdapter.isDiscovering()){
showToast("Making your device Discoverable");
Intent intent = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
mDiscoverBtLauncher.launch(intent);
}
}
});
mOffBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if(mBlueAdapter.isEnabled()){
mBlueAdapter.disable();
showToast("Turning Bluetooth off");
mBlueTv.setImageResource(R.drawable.ic_action_off);
}
else{
showToast("Bluetooth is already off");
}
}
});
The error is on the following line:
mBlueAdapter.isDiscovering()
mBlueAdapter.disable();
Error:
Call requires permission which may be rejected by user: code should explicitly check to see if permission is available (with `checkPermission`) or explicitly handle a potential `SecurityException`
This is my manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools">
<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
<uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />
<uses-permission android:name="android.permission.BLUETOOTH_SCAN" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<application
android:allowBackup="true"
android:dataExtractionRules="@xml/data_extraction_rules"
android:fullBackupContent="@xml/backup_rules"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/Theme.Bluetooth"
tools:targetApi="31">
<activity
android:name=".MainActivity"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
and this is the permisstions I added to manifest:
<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
<uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />
<uses-permission android:name="android.permission.BLUETOOTH_SCAN" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
I don't know how to solve this problem.
I need your help.
I added permission to manifest. But the problem was left.
