共享preferences没有设置boot_received广播接收机内部布尔 [英] Shared preferences not setting boolean inside boot_received broadcast receiver

问题描述

我想创建开始就启动我的服务选项。广播接收机本身的伟大工程，但是当我在选项添加它从来没有它设置为true。这里是code。

 公共无效的onReceive（上下文的背景下，意图意图）{
    字符串行动= intent.getAction（）;    如果（action.equals（Intent.ACTION_BOOT_COMPLETED））{
      共享preferences preFS = context.getShared preferences（startatboot，0）;
      布尔startatboot = prefs.getBoolean（startatboot，FALSE）;
      如果（startatboot）{
          context.startService（新意图（上下文，MyService.class））;
      }
 

解决方案

我不得不改变了...

 共享preferences preFS = context.getShared preferences（startatboot，0）;
 

这...

 共享preferences preFS = preferenceManager.getDefaultShared preferences（背景）;公共无效的onReceive（上下文的背景下，意图意图）{
    字符串行动= intent.getAction（）;    如果（action.equals（Intent.ACTION_BOOT_COMPLETED））{
      共享preferences preFS = preferenceManager.getDefaultShared preferences（背景）;
      布尔startatboot = prefs.getBoolean（startatboot，FALSE）;
      如果（startatboot）{
          context.startService（新意图（上下文，MyService.class））;
      }
 

I am trying to create the option to start my service on boot. The broadcast receiver works great by itself, but when I add in the option it never sets it to true. Here is the code.

public void onReceive(Context context, Intent intent) {
    String action = intent.getAction();

    if (action.equals(Intent.ACTION_BOOT_COMPLETED)) {
      SharedPreferences prefs = context.getSharedPreferences("startatboot",0);
      boolean startatboot = prefs.getBoolean("startatboot", false);
      if (startatboot) {
          context.startService(new Intent(context, MyService.class));
      }

解决方案

I had to change this...

SharedPreferences prefs = context.getSharedPreferences("startatboot",0);

to this...

SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);



public void onReceive(Context context, Intent intent) {
    String action = intent.getAction();

    if (action.equals(Intent.ACTION_BOOT_COMPLETED)) {
      SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);
      boolean startatboot = prefs.getBoolean("startatboot", false);
      if (startatboot) {
          context.startService(new Intent(context, MyService.class));
      }
