Android Studio中發生[INSTALL_FAILED_OLDER_SDK]失敗？

Question

我在Android Studio中導入了一個項目，但出現以下錯誤：

pkg: /data/local/tmp/mindmine.com.welcometol
Failure [INSTALL_FAILED_OLDER_SDK]

而貝婁是我的build.gradle ，我將minSdkVersion 21更改為minSdkVersion 8但仍然出現錯誤：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "mindmine.com.welcometol"
        minSdkVersion 21
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:recyclerview-v7:21.0.3'
    compile 'com.android.support:cardview-v7:21.0.3'
}

Answer 1

我認為您在清單中將minSdkVersion 21更改為minSdkVersion 8

在您的Gradle中更改

defaultConfig {
        applicationId "mindmine.com.welcometol"
        minSdkVersion *<Put yoru min SDK here>*
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
