尝试使用意图安装 apk 失败且没有错误 [英] Trying to install apk with intent fails without error

问题描述

我在下载后尝试安装 apk.
下载工作正常，但当我尝试安装该软件包时，它完全没有任何作用.
没有日志消息，我不知道我的错误可能是什么.

I'm trying to install an apk after I downloaded it.
Download works fine but when I try to install the package it does absolutely nothing.
There are no log messages and I have no clue what the my error might be.

这是我用来启动意图的代码(它肯定会被执行):

Here is the code I use to launch the intent (it definitely gets executed):

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
    Uri contentUri = FileProvider.getUriForFile(context, context.getApplicationContext().getPackageName() + ".provider", apkFile);
    Intent install = new Intent(Intent.ACTION_INSTALL_PACKAGE);
    install.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
    install.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
    install.putExtra(Intent.EXTRA_NOT_UNKNOWN_SOURCE, true);
    install.addCategory(Intent.CATEGORY_DEFAULT);
    install.setDataAndType(contentUri, "application/vnd.android.package-archive");
    context.startActivity(install);
} else {
    Intent install = new Intent(Intent.ACTION_INSTALL_PACKAGE);
    install.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    install.setDataAndType(Uri.fromFile(apkFile), "application/vnd.android.package-archive");
    context.startActivity(install);
}

我已经检查了变量:

• apkFile: "/storage/emulated/0/Download/name.apk"
• contentUri: "content://APP_ID.provider/external_storage_root/Download/name.apk"

非常感谢任何关于我可以尝试的提示.

Any tips on what I could try are greatly appreciated.

推荐答案

没关系，我在 AndroidManifest.xml 中打错了字.

Nevermind I made a typo in my AndroidManifest.xml.

情况如何:

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

应该如何:

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

注意到末尾有一个空格吗?
我花了 3 天时间才找到它...

Notice that one space at the end?
Took me 3 days to find it...
