If no such API application is available, you should declare the minimum supported version as API Level 14:...The Minsdkversion attribute declares the minimum version with which your app is compatible and the Targetsdkversion Attri Bute declares the highest version on which you ' ve optimized your app.The Minsdkver
Gradle Learning: the basis for custom building and gradle Building1. Configure the Manifest File
You can configure applicationId, minSdkVersion, targetSdkVersion, versionCode, and versionName directly by building a file instead of the manifest file. In addition, we can control the following attributes:TestApplicationId: applicationId testInstrumentationRunner: name of the JUnit test runner for the instrument test APK, used to run the signingConfig: pr

Actionbar Introduction Method:
There are several, starting with the Android 3.0 (API lever 11), all activity using the Theme.holo theme (or its subclasses) contains action Bar, when Targetsdkversion or minsdkversion property is set to "11" or greater, it is the default theme. In order to be compatible with the earlier versions of Android3.0, Actionbar is typically implemented through the appcompatactivity implementation of extends integration support

Android6.0 Run time permissions:
Given the relatively less secure version rights management prior to 6.0, Android 6.0 adopts a new permission model that only tells the user whether to authorize it at runtime time, rather than when it was originally installed, and by default every time the page is opened at run time, You need to check to see if

Version control is an important part in the process of program upgrade/maintenance.
You need to know the version of the application installed on the device and the versions that can be upgraded.
Other applications-including other programs you release-need to query the system for the version of your application to determine the compatibility between them.
You may also need to query the version of the Service released by your application to display it to users.

The error "Failure [INSTALL_FAILED_OLDER_SDK]" is reported if you want to run a program written in Android 2.3.3 (the corresponding sdk version is 10.
Analysis and Solution Process:
This is because the "minSdkVersion" is defined in the "AndroidManifest. xml" file under the program source code. You can delete it to solve the problem.
