I had a similar issue and it was because I was trying to install an apk on a phone with a previous version of the same apk, and both apks hadn't been signed with the same certificate. I mean when I used the same certificate I was able to overwrite the previous installation, but when I changed the certificate between versions, the installation was not possible. Are you using the same certificate?

I recently targeted android 12 and had to put <code>android:exported</code> attribute in my manifest components, but did not know what to put as the value. changing the value to <code>android:exported=&quot;true&quot;</code> worked.

blocks|key|1086939|text|如果您在AndroidManifest.xml中声明了两次MainActivity，就会发生这种情况。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1086940|另一个可能的原因是:您更改了启动活动。提示:永远不要在已经发布的应用程序中这样做！在Android+Developers+blog中讨论了原因。|offset|length|1086941|entityMap|0|LINK|mutability|MUTABLE|url|http://android-developers.blogspot.com/2011/06/things-that-cannot-change.html^0|0|16|N|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

This can happen if you have your MainActivity declared twice in your AndroidManifest.xml.

Another possible reason: you changed the launch activity. Hint: never do it with already published applications! Reasons discussed in <a href="http://android-developers.blogspot.com/2011/06/things-that-cannot-change.html">Android Developers blog</a>.

Sideloading debug apps for testing on a physical phone worked reliably until I upgraded the phone from Android Pie to Android 10. After that, the "App not installed" error came up every time I tried to sideload the app.

Based on a warning in my AndroidManifest.xml, I changed from...

<pre><code>&lt;application
 android:name=".App"
 android:allowBackup="true" ... /&gt;
</code></pre>

to...

<pre><code>&lt;application
 android:name=".App"
 android:allowBackup="false" ... /&gt;
</code></pre>

After that, I was able to sideload my app -- once. Then, I encountered the same "App not installed" error again. By changing <code>allowBackup</code> back to <code>true</code>, it worked again (at least once).

It is obvious from the number of answers and the variation in the answers that there are many reasons for this problem. I'm sharing this in case it helps others.

My problem was similar to that of @Lunatikzx. Because of wrong permission tag which was written as attribute to application:

<pre><code>&lt;application
 android:permission="android.permission.WRITE_EXTERNAL_STORAGE"
 android:label="@string/app_name"
 android:icon="@drawable/ic_launcher"
 android:testOnly="false"
 android:debuggable="true"&gt;
</code></pre>

What fixed it for me was changing permission tag to separate tag like this:

<pre><code>&lt;uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /&gt;
</code></pre>

blocks|key|1087547|text|显然，这也可能是由于在安装之前重命名APK造成的。我想通过缩短文件名来减少用户从我们的网站上获取应用程序所需的打字量。在那之后，他们无法安装它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1087548|一旦我恢复到创建和签名包时使用的原始文件名，我就能够更新已安装的应用程序。|1087549|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Apparently this can also be caused by renaming the APK prior to installing it. I wanted to reduce the amount of typing users had to do to get the app from our web site by shortening the file name. After that, they were unable to install it.

Once I reverted to the original file name used when creating and signing the package I was able to update the installed app.

blocks|key|1087859|text|在我的例子中，这是因为我使用的是支持库28的alpha版本。看起来谷歌将这些预发布版本标记为testOnly。如果你真的想像这样发布(例如，你想像我一样推出一个内部测试版)，你可以在你的gradle.properties文件中添加下面这行：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1087860|android.injected.testOnly=false|code-block|syntax|javascript|1087861|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

In my case it was because I was using the alpha version of support library 28. Looks like Google marks these pre release versions as testOnly. If you really want to release like this (for instance, you want to push an internal beta like I did), you can add this line to your gradle.properties file:

<pre><code>android.injected.testOnly=false

I had a similar situation.I was able to install app in debug mode using USB but not a signed version. I was able to install signed version on other phone, but not on my device. Numerous reasons and solutions did not help me. But one direction I got from a solution &quot;uninstall for all users&quot;.
What I did is to again install app in debug mode using USB connection, go to app details and &quot;uninstall for all users&quot; from right top 3 dots - to remove debug version. This looks like cleared all kinds of references. I usually do a normal uninstall.
Now I am able to get signed APK on the device and install and its success.

I found that if I built my app with compileSdkVersion, buildToolsVersion, and targetSdkVersion all set to the default value of 30 in my build.gradle file, then the app would not install on my phone. However, if I changed them back down to version 29, it worked. What the issue turned out to be was that from SDK 30 onwards you need to select V2 jar signing.

I ran into this when I had a bug with my custom build tool that would use ADT with a certificate intended for iOS (It certainly wasn't my first guess, since there doesn't seem to be anything special about the Android certificates other than only you should have one, they are just RSA-1024 certs, even self-signed is ok, at least for non-marketplace installs).

If you tried all the answers above and none of them worked, you might want to try this:

I have a program working in the Android Emulator. Every now and again I have been creating a signed .apk and exporting it to my HTC Desire to test. It has all been fine.

On my latest exported .apk I get the error message 'App not installed' when I try to install the .apk. It runs fine on the emulators.

As I have mainly been testing on the emulators and only every now and again exporting to a real phone I am not sure when this happened. What is the likely cause of it not installing on a physical phone but running fine in the emulators?

I have tried rebooting the phone &amp; removing the existing .apk, does not fix the fault.
