How to create an app supports old SDK versions (minSdkVersion) in android
When the wizard creates a new project and gives errors, then he is so frustrated.
I just create a new project with MinSdk = 9 to make the app work on gingerbread it gives me the following error:
Error:Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed : uses-sdk:minSdkVersion 9 cannot be smaller than version 14 declared in library [com.android.support:appcompat-v7:26.0.0-alpha1] C:\Users\USER\.android\build-cache\dfb3187f39ea1ff94009f5d34353fff5cfc3daee\output\AndroidManifest.xml
Suggestion: use tools:overrideLibrary="android.support.v7.appcompat" to force usage
and here is the gradle file
apply plugin: 'com.android.application'
android {
compileSdkVersion 26
buildToolsVersion "26.0.0"
defaultConfig {
applicationId "com.example.com.testApp"
minSdkVersion 9
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:26.0.0-alpha1'
testCompile 'junit:junit:4.12'
}

You must use an older version of the support library.
compileSdkVersion 25
compile 'com.android.support:appcompat-v7:25.4.0'
As you can find out in the release notes for 26.0.0 here
Note. The minimum SDK version has been increased to 14. As a result, many APIs that only existed for API <14 were deprecated. Clients of these APIs should migrate equivalents into their framework as indicated on the reference page for each deprecated API.
