[FIXED] I get "Call requires API level X (current min is Y)" even though I changed min to X

Issue

I try to call this code:

webView = findViewById(R.id.webView);
WebSettings settings = webView.getSettings();
settings.setMixedContentMode(WebSettings.MIXED_CONTENT_COMPATIBILITY_MODE);

But I get Call requires API level 21 (current min is 16)

So I opened build.gradle and changed minSdkVersion 16 to minSdkVersion 21

apply plugin: 'com.android.application'

android {
compileSdkVersion 28
defaultConfig {
    applicationId "my_id"
    minSdkVersion 21
    targetSdkVersion 28

I also added:

<uses-sdk
    android:minSdkVersion="21"
    android:targetSdkVersion="27"
/>

to the AndroidManifest.xml.

But it still shows the message Call requires API level 21 (current min is 16)

Solution

For such issues you can do two things:

1. Android Studio gets better and better but gradle integration still causes some problems so just invalidate cache and reload AS (Invalidate Caches / Restart).

2. You can trace how AndroidManifest.xml is build - it's merged from manifests in every module. First check app/build/intermediates/merged_manifests/{buildType}/AndroidManifest.xml - it's final manifest file that will be put in APK. If you find not expected values there, as next step find how it was merged - inspect: app/build/outputs/logs/ reports. For example if you discover that some library require bigger minSdk, you can override it in your app manifest:

   <uses-sdk android:targetSdkVersion="14" android:minSdkVersion="2" tools:overrideLibrary="com.example.lib1, com.example.lib2"/>

   and just make sure that older devices don't execute lib code that requires newer sdks.
