add adb ,gradle on your path
You can see this article How to adb into your path

You can see the Tinker wiki.
https://github.com/Tencent/tinker/wiki

1.DownLoad the source code of tinker from github
git clone git@github.com:Tencent/tinker.git

2.Open the Sample project
cd tinker/tinker-sample-android

3.DownLoad the dependencies of sample,It may take a long time when you run firstly,you can drink a cup of coffee.

4.Buid debug apk
gradle assembleDebug

5.Install the debug base apk into your phone or emulator(e.g. Genymotion,Bluestacks)
adb uninstall tinker.sample.android && adb install app/build/bakApk/*.apk

6.Start the debug base apk
adb shell am start tinker.sample.android/.app.MainActivity

7.Change some codes in order to fix bugs

TODO:// Coding in order to fix bug1
TODO:// Coding in order to fix bug2

e.g.Change the Log TAG of MainActivity

one: get row of TAG
grep -n "TAG" app/src/main/java/tinker/sample/android/app/MainActivity.java | head -n 1 | cut -d ":" -f 1

two: Replace the TAG to your tag eg:TestTinker
sed -i '42s/.*/private static final String TAG = "TestTinker";/' app/src/main/java/tinker/sample/android/app/MainActivity.java

three: confirm the change successfully
grep -n "TestTinker" app/src/main/java/tinker/sample/android/app/MainActivity.java

8.Get the base debug apk fileName
find app/build/bakApk/ -type f -name *.apk -print | xargs ls -ltr | head -n 1 | awk '{print $9}' | cut -d "/" -f 4

9.Get “tinkerOldApkPath” first occurrence of rows which from tinker-sample-android/app/build.gradle
grep -n "tinkerOldApkPath" app/build.gradle | head -n 1 | cut -d ":" -f 1

10.Change the config of app/build.gradle to Updte the tinkerOldApkPath

Replace the line numbers which from number9 and apkName which from number8

e.g.

number8 app-debug-1130-12-54-43.apk
number9 147

thus,you can get the command.

sed -i ‘number8s/.*/tinkerOldApkPath=”${bakPath}\/number9”/’ app/build.gradle

e.g.
sed -i '147s/.*/tinkerOldApkPath="${bakPath}\/app-debug-1130-12-54-43.apk"/' app/build.gradle

11.confirm the number11 do successfully

grep -n “number8” app/build.gradle

e.g.
grep -n "app-debug-1130-12-54-43.apk" app/build.gradle

12.Build in order to the patch apk
gradle tinkerPatchDebug

13.Push patch apk into phone or emulator
adb push app/build/outputs/tinkerPatch/debug/patch_signed_7zip.apk /sdcard/

14.Click LOADPATH Button on the Sample App
