Make sure the build variantis set to debug(and not release) in Android Studio (check the build variantspanel).

确保在 Android Studio中将构建变体设置为debug（而不是release）（检查构建变体面板）。

If set to debug, it should automatically sign the app with the auto-generated debug keystore, without editing the build scripts.

如果设置为调试，它应该使用自动生成的调试密钥库自动签署应用程序，而无需编辑构建脚本。

However you will need to create and configure a specific keystore for release.

但是，您需要为发布创建和配置特定的密钥库。

Always sign your build using your build.gradle DSL script like this:

始终使用 build.gradle DSL 脚本对您的构建进行签名，如下所示：

    android {
    signingConfigs {
        debug {
            storeFile file("debug.keystore")
        }

        myConfig {
            storeFile file("other.keystore")
            storePassword "android"
            keyAlias "androidotherkey"
            keyPassword "android"
        }
    }

    buildTypes {
        bar {
            debuggable true
            jniDebugBuild true
            signingConfig signingConfigs.debug
        }
        foo {
            debuggable false
            jniDebugBuild false
            signingConfig signingConfigs.myConfig
        }
    }
}

signingConfigs should be before buildTypes

signingConfigs 应该在 buildTypes 之前

signingConfigs {
        debug {

        }

The app project you downloaded may include a signed info in the file of build.gradle. If you saw codes like these:

您下载的应用项目可能在 build.gradle 文件中包含签名信息。如果你看到这样的代码：

buildTypes {
    debug {
        signingConfig signingConfigs.release
    }
    release {
        signingConfig signingConfigs.release
    }
}

you could delete them and try again.

你可以删除它们然后再试一次。

For security reasons, you cannot install an unsigned apk on Android. So if you only have the unsigned apk: you must sign it. Here is how to do that : link

出于安全原因，您不能在 Android 上安装未签名的 apk。因此，如果您只有未签名的 apk：您必须对其进行签名。这是如何做到的：链接

Note that you can sign the apk with a self-signed certificate.

请注意，您可以使用自签名证书对 apk 进行签名。

An alternative can be either :

另一种选择可以是：

• to download the signed apk if available.
• to download the sources, compile them (with Android-Studio or gradle or ...). It will produce multiple apks and one of them will be signed with your debug-key (and so you will be able to install it)

• 下载已签名的 apk（如果可用）。
• 下载源代码，编译它们（使用 Android-Studio 或 gradle 或 ...）。它将生成多个 apk，其中一个将使用您的调试密钥进行签名（因此您将能够安装它）
