Answer 1

Use this in your code before making any network call

/**
 * Initialize SSL
 * @param mContext
 */
public static void initializeSSLContext(Context mContext){
    try {
        SSLContext.getInstance("TLSv1.2");
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    }
    try {
        ProviderInstaller.installIfNeeded(mContext.getApplicationContext());
    } catch (GooglePlayServicesRepairableException e) {
        e.printStackTrace();
    } catch (GooglePlayServicesNotAvailableException e) {
        e.printStackTrace();
    }
}

I had the same problem and this piece of code solved my problem. FYI: I was using retrofit library for making network calls

You need to include below line in build.gradle

implementation 'com.google.android.gms:play-services-safetynet:17.0.0
