Android Studio混淆：

build.gradle中

 

1 2 3 4 5 6

buildTypes {         release {             minifyEnabled true             proguardFiles getDefaultProguardFile(‘proguard-android.txt‘), ‘proguard-rules.pro‘         }     }

minifEnabled 改为 true；

Android Studio 避免混淆第三方lib：

我这里用的是waps的lib，在proguard-rules.pro文件中加入

 

1 2 3 4 5

-dontwarn android.support.** -keep public class cn.waps.** {*;} -keep public interface cn.waps.** {*;} -dontwarn cn.waps.** -ignorewarnings

 

Drawer的箭头指示器：

使用ToolBar代替ActionBar，添加support-v7的ActionBarDrawerToggle即可。

Drawer覆盖ToolBar：

将ToolBar放入DrawerLayout的第一个子View中即可

获取Root权限并以Root身份执行linux命令的例子：

 

 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

//su权限         try {             process= Runtime.getRuntime().exec("su");             os=new DataOutputStream(process.getOutputStream());             is=new DataInputStream(process.getInputStream());             os.writeBytes("mount -o remount -o rw /system"+ " \n");               //>为覆盖，>>为追加             os.writeBytes("echo ‘"+response+"‘ > /etc/hosts" + " \n");             os.writeBytes(" exit \n");             os.flush();             InputStreamReader reader=new InputStreamReader(is);             StringBuilder builder=new StringBuilder();             int ch;             while ((ch=reader.read())!=-1){                 builder.append((char)ch);                 System.out.print((char)ch);             }             Log.i("RES",builder.toString());             mListener.onComplete();             button.setProgress(100);               process.waitFor();         } catch (IOException e) {             e.printStackTrace();         } catch (InterruptedException e) {             e.printStackTrace();         }

 

Voelly添加Header信息的方法：

 

 

 

 

 

 

 

Java

 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

StringRequest stringRequest = new StringRequest(Request.Method.GET,hostsUrl,                 new Response.Listener<String>() {                     @Override                     public void onResponse(String response) {                                              }                 }, new Response.ErrorListener() {             @Override             public void onErrorResponse(VolleyError error) {                 Log.e("TAG", error.getMessage(), error);             }         }){             //设置header信息             @Override             public HashMap<String, String> getHeaders() {                 HashMap<String, String> params = new HashMap<String, String>();                 String header="header";                 params.put("header1", header);                 return params;             }         };
