OperationFailedException: Installation failed

Im working on game develop in Unity. I want to make a game of Android. I downloaded the jdk, spk, etc.

I followed exacly how the videos told me but when I connect my Android to the game and click on "Build And Run" I get the error in the end of the process: Failed to build APK!.

The console shows:

OperationFailedException: Installation failed. See the Console for details. UnityEditor.Android.AndroidDeploymentTargetsExtension.UploadAPK (UnityEditor.BuildReporting.BuildReport buildReport, UnityEditor.Android.AndroidDevice device, UnityEditor.ProgressTaskManager taskManager) UnityEditor.Android.AndroidDeploymentTargetsExtension+c__AnonStorey1.<>m__0 () UnityEditor.ProgressTaskManager.Run () (at C:/buildslave/unity/build/Editor/Mono/Utils/ProgressBarUtils.cs:71) UnityEditor.Android.AndroidDeploymentTargetsExtension.LaunchBuildOnTarget (UnityEditor.BuildReporting.BuildReport buildReport, DeploymentTargetId targetId, UnityEditor.ProgressHandler progressHandler) UnityEditor.DeploymentTargets.DeploymentTargetManager.LaunchBuildOnTarget (BuildTargetGroup targetGroup, UnityEditor.BuildReporting.BuildReport buildReport, DeploymentTargetId targetId, UnityEditor.ProgressHandler progressHandler) (at C:/buildslave/unity/build/Editor/Mono/DeploymentTargets/DeploymentTargetManager.cs:36) UnityEditor.PostprocessBuildPlayer+c__AnonStorey0.<>m__1 () (at C:/buildslave/unity/build/Editor/Mono/BuildPipeline/PostprocessBuildPlayer.cs:181) UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

What could be the problem?

There are many reasons why this error can appear. Here are the most four known reasons why this is happening(arranged from very likely to unlikely order):

1.Your Minimum API Level in Unity is set to a higher API level than the actual version of your device/phone.

Go to Edit --> Project Settings --> Player --> Other Settings --> Identification --> Minimum API Level then change that to match your OS version.

2.Unity is trying to install your apk in a location you don't have permission to write to.

Go to Edit --> Project Settings --> Player --> Other Settings --> Configuration --> Install Location then change that to Automatic.

If build doesn't work, try the Prefer External then Force Internal. If none of them worked, roll back to Automatic as that is recommended option.

3.There is already app with the-same package name installed on your device. Consider changing your package name.

Go to Edit --> Project Settings --> Player --> Other Settings --> Identification --> Package Name then change that to new name.

You can also remove/uninstall the app from your device first.

4.Your device hardware/peripheral

It is harder to fix this issue when #1 to #3 did not solve it. The problem is now likely your device or any peripherals you are using. Here are the possible reasons and fix:

A.USB cable. - Try another cable.

B.USB hub on your computer- Try another one on the computer.

C.Battery. - A defective battery can also cause this. If the battery is swollen then it extreme likely that this is the issue. Replace the battery if you notice this.

D. Corrupted storage. - This happens sometimes and it is the problem, perform hard reset on the Android device.
