1. 判断程序是否运行在模拟器上
boolean isRunningInEmualtor() {
boolean qemuKernel = false;
Process process = null;
DataOutputStream os = null;
try{
process = Runtime.getRuntime().exec("getprop ro.kernel.qemu");
os = new DataOutputStream(process.getOutputStream());
BufferedReader in = new BufferedReader(new InputStreamReader(process.getInputStream(),"GBK"));
os.writeBytes("exit\n");
os.flush();
process.waitFor();
// getprop ro.kernel.qemu == 1 在模拟器
// getprop ro.product.model == "sdk" 在模拟器
// getprop ro.build.tags == "test-keys" 在模拟器
qemuKernel = (Integer.valueOf(in.readLine()) == 1);
Log.d("com.droider.checkqemu", "检测到模拟器:" + qemuKernel);
} catch (Exception e){
qemuKernel = false;
Log.d("com.droider.checkqemu", "run failed" + e.getMessage());
} finally {
try{
if (os != null) {
os.close();
}
process.destroy();
} catch (Exception e) { }
Log.d("com.droider.checkqemu", "run finally");
}
return qemuKernel;
}
2. 检测keystore签名,再与之前得做比较
public int getSignature(String packageName) {
PackageManager pm = this.getPackageManager();
PackageInfo pi = null;
int sig = 0;
try {
pi = pm.getPackageInfo(packageName, PackageManager.GET_SIGNATURES);
Signature[] s = pi.signatures;
sig = s[0].hashCode();
} catch (Exception e1) {
sig = 0;
e1.printStackTrace();
}
return sig;
}
3. 检测包名,版本名和版本号,然后做判断:
private String getAppInfo() {
try {
String pkName = this.getPackageName();
String versionName = this.getPackageManager().getPackageInfo(
pkName, 0).versionName;
int versionCode = this.getPackageManager()
.getPackageInfo(pkName, 0).versionCode;
return pkName + " " + versionName + " " + versionCode;
} catch (Exception e) {
}
return null;
}
4. 把jpg图片写成是png格式得图片 但是最新版本的apktool已经修复了
5. 花指令,影响jd-gui 但是最新版本的jd-gui已经修复
private static final char[] wJ = "0123456789abcdef".toCharArray();
public static String imsi = "204046330839890";
public static String p = "0";
public static String keyword = "电话";
public static String tranlateKeyword = "%E7%94%B5%E8%AF%9D";
在每个类里面加入 如上字段。。。。
