시스템바를 없앨 수 있다.

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    RootTools.debugMode = true; // debug mode

    hideSystemBar();
}
private void showSystemBar() {
    String commandStr = "am startservice -n com.android.systemui/.SystemUIService";
    runAsRoot(commandStr);
}

private void hideSystemBar() {
    try {
      //REQUIRES ROOT
      Build.VERSION_CODES vc = new Build.VERSION_CODES();
      Build.VERSION vr = new Build.VERSION();
      String ProcID = "79"; //HONEYCOMB AND OLDER

      //v.RELEASE //4.0.3
      if (vr.SDK_INT >= vc.ICE_CREAM_SANDWICH) {
          ProcID = "42"; //ICS AND NEWER
      }

      String commandStr = "service call activity " + ProcID + " s16 com.android.systemui";
      runAsRoot(commandStr);
    } catch (Exception e) {
      // something went wrong, deal with it here
    }
}

private void runAsRoot(String commandStr) {
    try {
      CommandCapture command = new CommandCapture(0, commandStr);
      RootTools.getShell(true).add(command).waitForFinish();
    } catch (Exception e) {
      // something went wrong, deal with it here
    }
}

}

System App을 개발하기 위해서는, 권한이 필요하다.
AndroidManifest.xml에 다음과 같이 sharedUserId를 설정해주면 된다.

android:sharedUserId="android.uid.system"

이렇게 설정된 시스템앱은 해당 플래폼의 key로 Signing되어야 하는데,
이러한 과정을 적어보려고 한다.

1. Framework에서 키 생성하기.

안드로이드 프레임웍의 /build/target/product/security 디렉토리를 보면 다음과 같은 파일이 확인된다.

2. 명령어

$ openssl pkcs8 -inform DER -nocrypt -in testkey.pk8 -out testkey.pem

$ openssl pkcs12 -export -in testkey.x509.pem -inkey testkey.pem -out testkey.p12 -password pass:android -name androiddebugkey

$ keytool -importkeystore -deststorepass android -destkeystore testkey.jks -srckeystore testkey.p12 -srcstoretype PKCS12 -srcstorepass android

3. SignKey for Emulator

두개의 파일을 이용해서 jks를 만들었더니 에뮬레이터에서도 잘 동작함.
