I just used android studio to develop, and there was such an error when running the program
Failure [INSTALL_FAILED_OLDER_SDK]
Solution: Check the build.gradle file:
apply plugin: ‘com.android.application’
android { compileSdkVersion 21 buildToolsVersion "22.0.0" defaultConfig { applicationId "com.aitwx.tab" minSdkVersion 19 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:appcompat-v7:21.0.3' }
It is found that minSdkVersion is 19, and the mobile phone version I installed is lower than 19, so an error is reported, which can be modified to 8.
