項目用了極光推送，但是在一些手機收不到通知翔试，上網(wǎng)搜索些資料轻要，首先感謝阿豪02、太書紅葉垦缅，整合一下冲泥，不足希望大家糾正。
1.獲取權(quán)限工具類
public class NotificationsUtils {
private static final String CHECK_OP_NO_THROW = "checkOpNoThrow";
private static final String OP_POST_NOTIFICATION = "OP_POST_NOTIFICATION";
@SuppressLint("NewApi")
public static boolean isNotificationEnabled(Context context) {
if (Build.VERSION.SDK_INT >= 24) {
return NotificationManagerCompat.from(context).areNotificationsEnabled() ;
} else if (Build.VERSION.SDK_INT >= 19) {
AppOpsManager appOps = (AppOpsManager) context.getSystemService(Context.APP_OPS_SERVICE);
ApplicationInfo appInfo = context.getApplicationInfo();
String pkg = context.getApplicationContext().getPackageName();
int uid = appInfo.uid;
try {
Class<?> 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 = (int) opPostNotificationValue.get(Integer.class);
return ((int) checkOpNoThrowMethod.invoke(appOps, value, uid, pkg) == AppOpsManager.MODE_ALLOWED);
} catch (ClassNotFoundException | NoSuchMethodException | NoSuchFieldException | InvocationTargetException | IllegalAccessException | RuntimeException e) {
return true;
}
} else {
return true;
}
}
}
2.?跳轉(zhuǎn)到應(yīng)用權(quán)限設(shè)置界面
if (!NotificationsUtils.isNotificationEnabled(this)) {
final AlertDialog dialog = new AlertDialog.Builder(this).create();
dialog.show();
View view = View.inflate(this, R.layout.dialog, null);
dialog.setContentView(view);
TextView context = (TextView) view.findViewById(R.id.tv_dialog_context);
context.setText("檢測到您沒有打開通知權(quán)限壁涎，是否去打開");
TextView confirm = (TextView) view.findViewById(R.id.btn_confirm);
confirm.setText("確定");
confirm.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
dialog.cancel();
Intent localIntent = new Intent();
localIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
if (Build.VERSION.SDK_INT >= 9) {
localIntent.setAction("android.settings.APPLICATION_DETAILS_SETTINGS");
localIntent.setData(Uri.fromParts("package", MainActivity.this.getPackageName(), null));
} else if (Build.VERSION.SDK_INT <= 8) {
localIntent.setAction(Intent.ACTION_VIEW);
localIntent.setClassName("com.android.settings", "com.android.settings.InstalledAppDetails"); localIntent.putExtra("com.android.settings.ApplicationPkgName", MainActivity.this.getPackageName());
} startActivity(localIntent);
}
});
TextView cancel = (TextView) view.findViewById(R.id.btn_off);
cancel.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
dialog.cancel();
}
});
}??
