deprecated warning while compiling

Question

i have a question regarding development environments settings. i am trying to see if there is any possibility to make a compilation warning in a development environment(eclipse,android studio)for android applications using a deprecated feature(could be a method , constructor or whatever you can think of ). until now i am working manually to find the use of this deprecated features , and my boss asked me to look for an automatic settings in my idea ...

so lets say for a specific code :

 protected void onPrepareDialog(int paramInt, Dialog paramDialog)
  {
    try
    {
      super.onPrepareDialog(paramInt, paramDialog);
      AlertDialog localAlertDialog = (AlertDialog)paramDialog;
      localAlertDialog.setTitle("Passphrase required");
      ((TextView)localAlertDialog.findViewById(2131230727)).setText(Preferences.getConfigName(this, getConfigFile()));
      Button localButton = localAlertDialog.getButton(-3);
      if (this.mOpenVpnService != null);
      for (boolean bool = true; ; bool = false)
      {
        localButton.setEnabled(bool);
        return;
      }

i have several deprecated features here , and android studio declares it , but what i need is a configuration for this warning to be automated and save me the need of walking through each class manually ...

Answer 1

For me the best solution is add this lines in the file build.gradle(project:appname)

allprojects {
tasks.withType(JavaCompile) {
    options.compilerArgs << "-Xlint:unchecked" << "-Xlint:deprecation"
}

Then all the deprecated methods in the java files appear in the build tab: deprecated api tab android studio

This works on gradle 5.1.1
