private boolean isNotificationEnabled(Context context) { String CHECK_OP_NO_THROW = "checkOpNoThrow"; String OP_POST_NOTIFICATION = "OP_POST_NOTIFICATION"; AppOpsManager mAppOps = (AppOpsManager) context.getSystemService(Context.APP_OPS_SERVICE); ApplicationInfo appInfo = context.getApplicationInfo(); String pkg = context.getApplicationContext().getPackageName(); int uid = appInfo.uid; Class appOpsClass = null; /* Context.APP_OPS_MANAGER */ try { appOpsClass = Class.forName(AppOpsManager.class.getName()); Method checkOpNoThrowMethod = appOpsClass.getMethod(CHECK_OP_NO_THROW, Integer.TYPE, Integer.TYPE, String.class); Field opPostNotificationValue = appOpsClass.getDeclaredField(OP_POST_NOTIFICATION); int value = (Integer) opPostNotificationValue.get(Integer.class); return ((Integer) checkOpNoThrowMethod.invoke(mAppOps, value, uid, pkg) == AppOpsManager.MODE_ALLOWED); } catch (ClassNotFoundException e) { e.printStackTrace(); } catch (NoSuchMethodException e) { e.printStackTrace(); } catch (NoSuchFieldException e) { e.printStackTrace(); } catch (InvocationTargetException e) { e.printStackTrace(); } catch (IllegalAccessException e) { e.printStackTrace(); } return false; } 跳转设置页面：
private void goToSet(){ if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.BASE) { // 进入设置系统应用权限界面 Intent intent = new Intent(Settings.ACTION_SETTINGS); startActivity(intent); return; } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {// 运行系统在5.x环境使用 // 进入设置系统应用权限界面 Intent intent = new Intent(Settings.ACTION_SETTINGS); startActivity(intent); return; } }更多相关文章
