Call requires API level 21, current min is 8

Question

Call requires API level 21, current min is 8. Even though I set my min SDK to 21, it still shows this error.

<uses-sdk android:minSdkVersion="21"
          android:targetSdkVersion="23"
          android:maxSdkVersion="23" />

Answer 1

The sdk version values in the Manifest.xml will be overridden by the values in the build.gradle file.

Please change the code in your build.gradle file to this.

android {
compileSdkVersion 23
buildToolsVersion "23.0.1"

defaultConfig {

    minSdkVersion 8
    targetSdkVersion 22

Answer 2

Look for your project properties file. This may be in your root folder, called project .properties. Try adding this line, you should have it in any case:

target=android-23

Answer 3

"Calls requires API level 21.(current mint is 15)"...

I solved this error by simply

set-> compileSdkVersion 27 minSdkVersion 15 TargetSdkVersion 27

After setting these attributes, I simply go main activity where I face a problem.

I just click on my error and from suggestions I choose Add @TargetApi(LOLLIPOP) Annotation and through this process, I solved my issue..
