有没有办法检查应用程序签名是否已调试或发布？

adb shell dumpsys package <package_name> | grep "debuggable"

adb shell dumpsys package <package_name> | grep "signatures"

import android.content.pm.PackageManager;
import android.content.pm.PackageInfo;
import android.content.pm.Signature;

public boolean isDebuggable(String packageName) {
    try {
        PackageInfo packageInfo = getPackageManager().getPackageInfo(packageName, PackageManager.GET_SIGNATURES);
        Signature[] signatures = packageInfo.signatures;
        for (Signature signature : signatures) {
            if ((signature.getFlags() & Signature.FLAG_DEBUGGABLE) != 0) {
                return true;
            }
        }
    } catch (PackageManager.NameNotFoundException e) {
        e.printStackTrace();
    }
    return false;
}
