我允许显示

<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
        package="com.example.android.softkeyboard">

    <uses-permission android:name="android.permission.KILL_BACKGROUND_PROCESSES"/>

    <application android:label="aabbccdd">


        <activity
            android:name=".CustomKeyboardActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity 
            android:name=".MakeKeyActivity"
            android:label="@string/app_name">
        </activity>
        <activity 
            android:name=".MakeDictionaryActivity"
            android:label="@string/app_name">
        </activity>
        <activity 
            android:name=".UpandDownActivity"
            android:label="@string/app_name">
        </activity>


        <service 
                android:exported="true"
                android:enabled="true" 
                android:name=".SoftKeyboard"
                android:permission="android.permission.BIND_INPUT_METHOD">
            <intent-filter>
                <action android:name="android.view.InputMethod" />
            </intent-filter>
            <meta-data android:name="android.view.im" android:resource="@xml/method" />
        </service>
        <uses-permission android:name="android.permission.BIND_INPUT_METHOD"/>

    </application>
</manifest>

我叫这段代码。

Intent intent=new Intent(this,SoftKeyboard.class);
stopService(intent);
startService(intent);

我允许但是，为什么请求许可？

Answer 1

看起来您将<uses-permission>元素作为<application>元素的子元素。它应与<application>元素下的<manifest>处于同一级别。

换句话说，改变最后几行：

    </service>
    <uses-permission android:name="android.permission.BIND_INPUT_METHOD"/>
  </application>
</manifest>

到此：

    </service>
  </application>
  <uses-permission android:name="android.permission.BIND_INPUT_METHOD"/>
</manifest>

android - 我想从活动开始服务
