using Context in a static environment [ 1051 views ]
Goal: get Context in a static method
Sometimes we need a context in a static method, but we don’t have… Let’s dig one.
public static Application getGlobalContext(){
try {
final Class<?> activityThreadClass = Class.forName("android.app.ActivityThread");
final Method method = activityThreadClass.getMethod("currentApplication");
return (Application) method.invoke(null, (Object[]) null);
} catch (final ClassNotFoundException e) { // handle exception
} catch (final NoSuchMethodException e) { // handle exception
} catch (final IllegalArgumentException e) { // handle exception
} catch (final IllegalAccessException e) { // handle exception
} catch (final InvocationTargetException e) { // handle exception
}
return null;
}
example: get the device ID (IMEI) in a static function.
public static String deviceID_IMEI(){
TelephonyManager tm =
(TelephonyManager)getGlobalContext().getSystemService(Context.TELEPHONY_SERVICE);
String device_id = tm.getDeviceId();
return device_id;
}
