在我的例子中，这是因为Android Studio 3.0设置Android:testOnly="true"在apk上，从版本build Variant构建。

所以运行。/gradlew assemblerrelease来解决我的问题

检查Android版本。

如果你安装的是非市场应用程序，和不兼容的版本，你会得到这个错误。

应用程序的目标是2.3.4 您的设备是2.2 然后你会得到这个错误。

在我的情况下，我删除无用的权限是不需要的

我只需要一个许可

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

并删除不需要的权限，并开始给出此错误

<uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />
<uses-permission android:name="android.permission.INSTALL_LOCATION_PROVIDER" />
<uses-permission android:name="android.permission.CONTROL_LOCATION_UPDATES" />

我的问题是:我使用了调试Apk，这是在我从Android Studio执行Run命令时生成的

解决方案是:不使用此文件，清除项目并单击Build > Build APK(s) from Android Studio。然后你可以使用生成的APK从通常的文件夹(app/build/outputs/ APK /debug/)

像这样生成的文件安装起来没有问题。

Clearly there are many causes of this problem. For me the situation was this: I had deployed to my nexus 7 (actual device) from within the Android Studio (v1.3.2). All worked fine. I then created a signed apk and uploaded to my Google Drive. After disconnecting my nexus from the usb, I went to the settings/apps and uninstalled my app (App1). I then opened google drive and clicked on my App1.apk and chose to install it (need to ensure you have allowed installation of apks in settings). Then I got the dreaded message "App not Installed"

Solution for me: go back into settings/apps and scroll though all apps and at the bottom was a pale version of my App1 (note the original App1 was at the top in Alphabetical order which was deleted as above). When clicking on the pale version it said "Not installed for this user". (I had set up my nexus to have more than one user). But in the top right corner there is a three dot button. I pressed this and it said "Uninstall for all users". Which I did and it fixed the problem. I was now able to click on App1.apk and it installed fine without the error.

我有同样类型的错误，这是由我的android manifest XML文件中的这一行引起的。

android:permission="android.permission.INSTALL_LOCATION_PROVIDER"

我去掉了那条线，问题就解决了。希望这能有所帮助
