Question

我正在构建具有系统级权限的应用，并由移动设备制造商签名。

已生成已签名的apk，但是当我尝试从菜单中打开应用程序时，它表示未安装应用程序。

以下是该应用的清单文件。欢迎任何建议

<?xml version="1.0" encoding="utf-8"?>
<manifest package="com.mjawaid.nwlogger"
      xmlns:android="http://schemas.android.com/apk/res/android"
      android:sharedUserId="android.uid.system">

<!-- <uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS"/> -->
<!-- <uses-permission android:name="android.permission.WRITE_SETTINGS"/> -->
<!-- <uses-permission android:name="android.permission.CONNECTIVITY_INTERNAL"/>
<uses-permission android:name="android.permission.MODIFY_PHONE_STATE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> -->

<!--<uses-feature android:name="android.hardware.telephony">
</uses-feature> -->

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme"
    android:sharedUserId="android.uid.system">
    <activity
        android:name="com.mjawaid.nwlogger.MainActivity"
        android:exported="false">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
    </activity>
    <activity android:name="com.mjawaid.nwlogger.NWOptionsActivity"/>
    <activity android:name="com.mjawaid.nwlogger.helper.silentlog.SilentLogSprdOption">
    </activity>
</application>

以下是app build.gradle，如果有帮助的话。

        }

                )

Answer 1

如果您拥有超级用户权限，请尝试手动将应用置于/system/priv-app内，然后重新启动设备并尝试从菜单中打开。

Answer 2

尝试清理构建，然后您需要创建签名的apk。

Answer 3

似乎错误是因为我将android:exported="false"添加到我的启动器活动中，这似乎导致了问题。

删除属性解决了我的问题。
