android - Firebase Analytics 和崩溃的权限

Question

我用过

//Analytics
compile 'com.google.firebase:firebase-core:9.2.1'
// Crash
compile 'com.google.firebase:firebase-crash:9.2.1'

并在我生成的 list 中获得了那些人:

<!-- Required permission for App measurement to run. -->
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<!-- Optional permission for App measurement to run. -->
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />

然后我们有下面的 block

<permission
    android:name="my.package.name.permission.C2D_MESSAGE"
    android:protectionLevel="signature" />
<uses-permission android:name="my.package.name.permission.C2D_MESSAGE" />

我的问题:

If I use only Firebase Analytics and Crash and don't need any messaging functional, is it Ok to remove the second block as follows:

<uses-permission android:name="my.package.name.permission.C2D_MESSAGE" tools:node="remove" />

What does it mean "Optional permission for App measurement to run" in the first block? Is it safe to remove that too?

Firebase Analytics 使用 FirebaseInstanceId。这可以通过在 Gradle 的 Android Studio 工具窗口中运行依赖项任务来查看。这部分输出显示了对 FirebaseInstanceId 的依赖:

C2D_MESSAGE 权限来自与 firebase-iid 库关联的 list 。我的猜测是，如果没有它，FirebaseAnalytics 将无法获得设备的唯一 ID，也无法报告数据。

关于 WAKE_LOCK 权限，请参阅 related answer .

我怀疑删除任何权限是否安全。您可以通过在没有它们的情况下运行并查看分析是否报告任何事件来找出答案。
