Question

我从app 1开始提供服务。此应用程序清单中的服务声明如下：

     <service android:name="jp.co.xyz.bluetooth.profile.TIPServer"
     android:permission="jp.co.abc.android.OMRSSettings.permission.Access" >
<intent-filter>
    <action android:name="jp.co.xyz.bluetooth.api.ICommonResultCallback" />
    <action android:name="jp.co.xyz.bluetooth.api.ITimeServer" />
</intent-filter>

我尝试从第二个应用绑定到此服务。第二个应用程序清单中的服务声明如下：

 <service android:name="jp.co.xyz.bluetooth.profile.TIPServer"
     android:permission="jp.co.abc.android.OMRSSettings.permission.Access" >
<intent-filter>
    <action android:name="jp.co.xyz.bluetooth.api.ICommonResultCallback" />
    <action android:name="jp.co.xyz.bluetooth.api.ITimeServer" />
</intent-filter>

以下是我用来从app 2进行bindservice的代码。

Intent time_intent = new Intent(ITimeServer.class.getName());
mContext.bindService(time_intent, time_connection, Context.BIND_AUTO_CREATE);

当我尝试绑定到已经从app 1启动的服务时，我收到以下异常。

当我删除app 1时，我会毫无问题地绑定到服务。

有人可以告诉我这个问题的原因和解决方案吗？

非常感谢任何帮助。

Answer 1

你错过了在你的清单中编写android：process =“：remote”... 你的声明应该是

 <service android:name="jp.co.xyz.bluetooth.profile.TIPServer" android:process=":remote">

android：process =“：remote”属性告诉Android在与应用程序其余部分分开的进程中运行我们的服务

Answer 2

使用此代码：

Intent intent = new Intent();
intent.setAction("com.action");
intent.setPackage("com.package.to.service");

服务已经启动时，bindservice失败
