解决真机 INSTALL_FAILED_TEST_ONLY安装失

在Android项目的主module下面的build.gradle文件中的android标签里面加入一下代码：

//解决真机 INSTALL_FAILED_TEST_ONLY安装失败的问题
    applicationVariants.all { variant ->
        if (variant.name.contains("debug")) {
            println("variant.name: " + variant.name);
            variant.outputs.each { output ->
                output.processManifest.doLast {
                    String manifestPath = "${buildDir}/intermediates/merged_manifests/${variant.name}/AndroidManifest.xml"
                    def manifestContent = file(manifestPath).getText('UTF-8')
                    manifestContent = manifestContent.replaceAll("android:testOnly=\"true\"", "android:testOnly=\"false\"")
                    file(manifestPath).write(manifestContent, 'UTF-8')
                }
            }
        }
    }
