android - Syncadapter 适用于手机但不适用于平板电脑

Question

我实现了一个简单的 syncadapter，它在 Moto G 上运行良好，但在 Nexus 7 上却不行(永远不会调用 onPerformSync)

为了测试，我像这样手动启动同步:

Bundle settingsBundle = new Bundle();
        settingsBundle.putBoolean(
                ContentResolver.SYNC_EXTRAS_MANUAL, true);
        settingsBundle.putBoolean(
                ContentResolver.SYNC_EXTRAS_EXPEDITED, true);
    /*
     * Request the sync for the default account, authority, and
     * manual sync settings
     */
     ContentResolver.requestSync(mAccount, DbContract.AUTHORITY, settingsBundle);

我的 manifest.xml 看起来像这样:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="app.com.jeldrik.teacherslittlehelper" >
<uses-permission android:name="android.permission.CALL_PHONE"/>
<uses-permission android:name="android.permission.AUTHENTICATE_ACCOUNTS"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.READ_SYNC_SETTINGS"/>
<uses-permission android:name="android.permission.WRITE_SYNC_SETTINGS"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" android:maxSdkVersion="18" />
<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <provider
        android:authorities="app.com.jeldrik.teacherslittlehelper.data"
        android:name="app.com.jeldrik.teacherslittlehelper.data.ClassContentProvider">
        </provider>

    <service
        android:name="app.com.jeldrik.teacherslittlehelper.DataTransfer.AuthenticatorService">
        <intent-filter>
            <action android:name="android.accounts.AccountAuthenticator"/>
        </intent-filter>
        <meta-data
            android:name="android.accounts.AccountAuthenticator"
            android:resource="@xml/authenticator" />
    </service>

    <service
        android:name="app.com.jeldrik.teacherslittlehelper.DataTransfer.SyncService"
        android:exported="true"
        android:process=":sync">
        <intent-filter>
            <action android:name="android.content.SyncAdapter"/>
        </intent-filter>
        <meta-data
            android:name="android.content.SyncAdapter"
            android:resource="@xml/syncadapter" />
    </service>

</application>

好吧，愚蠢的错误和简单的解决方案:Android 发出警告说我的平板电脑内存快满了。似乎在这种情况下所有同步都被自动禁用。删除了一些东西，现在可以同步了:P
