java - 启动服务时不允许绑定(bind)服务Intent

Question

我现在正在开发一个Android应用程序。当我想启动一个服务时，我遇到了问题:不允许绑定(bind)到服务Intent。该服务为Yotaphone背屏服务。

我搜索问题，资料很少，大部分都不是同一类问题。我不知道哪个部分出了问题。

我了解说明: http://mwiki.yotaphone.com/wiki/Building_First_App .

MainActivity 中的 onStart() 函数:

@Override
protected void onStart() {
    super.onStart();
    Intent bsIntent = new Intent(this, MyBSActivity.class);
    this.startService(bsIntent);

}

Yotaphone 背屏服务:

public class MyBSActivity extends BSActivity {
@Override
protected void onBSCreate() {
    super.onBSCreate();
    setBSContentView(R.layout.bs_activity);
}}

错误描述:

    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

    </activity>


    <!-- Service for working with a back screen -->
    <service
        android:name=".MyBSActivity"
        android:exported="true" />

    <!-- Adding YotaPhone SDK library -->
    <uses-library
        android:name="com.yotadevices.yotaphone2.sdk.v2"
        android:required="true" />
</application>

我遇到了完全相同的问题，首先想到的是当前的系统应用程序还不支持新的SDK。然而，我只是尝试反编译现有的 Yota 应用程序，发现我们需要包含权限。教程没有提到的东西。

因此，要解决您(我们的)问题，您需要在 AndroidManifest.xml 中包含以下权限:

<uses-permission android:name="com.yotadevices.framework.permission.ACCESS_BACKSCREEN" />

祝你编码愉快!
