Had the same error, with a much newer version of Android Studio (version 4.1) . A fresh install of Android Studio + a fresh "basic Activity" template would run into error type 3 for hours. I am on win 10 - my problem was how to kill the gradle cache. A good answer above showed a screen snapshot from gradle, but i didn't find it in Android Studio 4.1. Also the env vars for gradle had not been set , and the commandline for gradle didn't work. So .. here is how it worked finally. I went to C:\Users\myusername\ .gradle. This has subdir "caches". I deleted everything inside. Worked ! I did close Android Studio before, restarted and then it worked nicely. Ah forgot one thing- i run the device emulator (defauöt device), i.e. no physical device yet.

如果您已经从设备手动卸载了应用程序，并且设置了多用户，则可能会发生此错误。需要从设备中的所有用户卸载该应用程序。

如果你从一个现有的项目中创建一个新项目:

build.gradle

defaultConfig {
        applicationId "xxxxxxxxx" //xxxxxxxxx should be "package name (com.demo.app) from AndroidMenifest.xml" 
        minSdkVersion 16
        targetSdkVersion 28
        versionCode 1
        versionName "3.0.0"
        ndk {
            abiFilters "armeabi-v7a", "x86"
        }
}

然后在Android Studio中单击同步

我有错误类型3。我设法通过在AndroidMainfest.xml中添加以下代码来修复它。

    <activity android:name=".GameActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

只是做一个干净的构建对我来说很有用。

要进行干净的构建，请执行以下操作:

Build -> Clean Project

然后在设备上进行构建或直接运行。

我在重命名/重构后也出现了同样的错误。我所做的就是将applicationId属性添加到我的构建中。Gradle文件，并将其值设置为应用程序包。

在build.gradle:

android {
defaultConfig {
    applicationId "com.example.myapp"  
  }
}
