Android Studio失败错误[INSTALL_FAILED_OLDER_SDK]

Question

Once I try to run my app in the emulator it sends me this error:

pkg: /data/local/tmp/com.cerocerouno.safr.aplicacionmisteriosa
Failure [INSTALL_FAILED_OLDER_SDK]

I try creating another device, and when I run the new one, the same error appears. And something else I notice that all the emulators have errors, when I touch the screen of any device I have created it collapses.

This is my build.gradle file:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 'android-L'
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "com.cerocerouno.safr.aplicacionmisteriosa"
        minSdkVersion 7
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:19.+'
}

Besides checking the right minSdkVersion in build.gradle , make sure you have installed all necessary tools and correct SDK Platform for your preferred Android Version in SDK Manager. In Android Studio klick on Tools -> Android -> SDK Manager . Then install at minimum (for Android 2.2 without emulator):

• Android SDK Tools
• Android SDK Platform-tools
• Android SDK Build-tools (latest)
• Android 2.2 (API 8)
• SDK Platform
• Google APIs

Also, Change targetSdkVersion 'L' to 19 in build.gradle file.

apply plugin: 'com.android.application'

android {
    compileSdkVersion 'android-L'
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "com.cerocerouno.safr.aplicacionmisteriosa"
        minSdkVersion 7
        targetSdkVersion 'L'  #change this to 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:19.+'
}
