新建项目，添加gradle依赖在项目的 build.gradle 中，添加tinker-patch-gradle-plugin的依赖

buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.2.0'
classpath ('com.tencent.tinker:tinker-patch-gradle-plugin:1.7.7')
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}allprojects {
repositories {
jcenter()
}
}task clean(type: Delete) {
delete rootProject.buildDir
}

在app的gradle文件，我们需要添加tinker的库依赖以及apply tinker的gradle插件.

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile "com.android.support:appcompat-v7:23.1.1"
compile("com.tencent.tinker:tinker-android-lib:1.7.7") { changing = true }
provided("com.tencent.tinker:tinker-android-anno:1.7.7") { changing = true }
compile "com.android.support:multidex:1.0.1"
}
//apply tinker插件
apply plugin: 'com.tencent.tinker.patch'

顺便加一下签名的配置，放在项目目录。

此时构建项目也许会遇到下面问题

在下面的build.gradle 中设置tinker 配置，具体请看下一段代码。

对tinker 进行配置，整个build.gradle文件如下所示。直接拷贝自己需要的就行。

apply plugin: 'com.android.application'
//apply tinker插件
apply plugin: 'com.tencent.tinker.patch'

android {
compileSdkVersion 25
buildToolsVersion "25.0.1"
defaultConfig {
applicationId "com.youxiake.tinkerdemo"
minSdkVersion 14
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
signingConfigs {
release {
try {
storeFile file("release.jks")
storePassword "testres"
keyAlias "testres"
keyPassword "testres"
} catch (ex) {
throw new InvalidUserDataException(ex.toString())
}
}
}

buildTypes {
release {
minifyEnabled true
signingConfig signingConfigs.release
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
debug {
debuggable true
minifyEnabled true
signingConfig signingConfigs.release
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.1.1'
testCompile 'junit:junit:4.12'
//可选，用于生成application类
provided('com.tencent.tinker:tinker-android-anno:1.7.7')
//tinker的核心库
compile('com.tencent.tinker:tinker-android-lib:1.7.7')

compile "com.android.support:multidex:1.0.1"
}

def bakPath = file("${buildDir}/bakApk/")

ext {
tinkerEnabled = true
tinkerOldApkPath = "${bakPath}/app-debug-0209-10-09-21.apk"
//proguard mapping file to build patch apk
tinkerApplyMappingPath = "${bakPath}/"
//resource R.txt to build patch apk, must input if there is resource changed
tinkerApplyResourcePath = "${bakPath}/app-debug-0209-10-09-21-R.txt"
}

def getOldApkPath() {
return ext.tinkerOldApkPath
}
def getApplyMappingPath() {
return ext.tinkerApplyMappingPath
}
def getApplyResourceMappingPath() {
return  ext.tinkerApplyResourcePath
}

if (ext.tinkerEnabled) {
tinkerPatch {
oldApk = getOldApkPath()
ignoreWarning = false
useSign = true

//        packageConfig {
//
//            configField("TINKER_ID", "2.0")
//        }
buildConfig{
tinkerId = "1.0"
applyMapping = getApplyMappingPath()
applyResourceMapping = getApplyResourceMappingPath()
}

lib {

pattern = ["lib/armeabi/*.so"]
}

res {

pattern = ["res/*", "assets/*", "resources.arsc", "AndroidManifest.xml"]

ignoreChange = ["assetsmple_meta.txt"]

largeModSize = 100
}

sevenZip {

zipArtifact = "com.tencent.mm:SevenZip:1.1.10"
}

dex {

dexMode = "jar"

pattern = ["classes*.dex",
"assetscondary-dex-?.jar"]

loader = ["com.tencent.tinker.loader.*",
"com.tencent.tinker.*",
"com.youxiake.tinkerdemo.SampleApplication"
]
}

}
}

android.applicationVariants.all { variant ->
/**
* task type, you want to bak
*/
def taskName = variant.name

tasks.all {
if ("assemble${taskName.capitalize()}".equalsIgnoreCase(it.name)) {
it.doLast {
copy {
def date = new Date().format("MMdd-HH-mm-ss")
from "${buildDir}/outputs/apk/${project.getName()}-${taskName}.apk"
into bakPath
rename { String fileName ->
fileName.replace("${project.getName()}-${taskName}.apk", "${project.getName()}-${taskName}-${date}.apk")
}

from "${buildDir}/outputs/mapping/${taskName}/mapping.txt"
into bakPath
rename { String fileName ->
fileName.replace("mapping.txt", "${project.getName()}-${taskName}-${date}-mapping.txt")
}

from "${buildDir}/intermediates/symbols/${taskName}/R.txt"
into bakPath
rename { String fileName ->
fileName.replace("R.txt", "${project.getName()}-${taskName}-${date}-R.txt")
}
}
}
}
}
}

添加(或修改)项目的 Application ,使之继承DefaultApplicationLike。

@SuppressWarnings("unused")
@DefaultLifeCycle(application = "com.youxiake.tinkerdemo.SampleApplication",
flags = ShareConstants.TINKER_ENABLE_ALL,
loadVerifyFlag = false)
public class SampleApplicationLike extends DefaultApplicationLike {
private static final String TAG = "Tinker.SampleApplicationLike";

public SampleApplicationLike(Application application, int tinkerFlags, boolean tinkerLoadVerifyFlag,
long applicationStartElapsedTime, long applicationStartMillisTime, Intent tinkerResultIntent) {
super(application, tinkerFlags, tinkerLoadVerifyFlag, applicationStartElapsedTime, applicationStartMillisTime, tinkerResultIntent);
}

/**
* install multiDex before install tinker
* so we don't need to put the tinker lib classes in the main dex
*
* @param base
*/
@TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)
@Override
public void onBaseContextAttached(Context base) {
super.onBaseContextAttached(base);
//you must install multiDex whatever tinker is installed!
MultiDex.install(base);

//installTinker after load multiDex
//or you can put com.tencent.tinker.** to main dex
TinkerInstaller.install(this);
}

@TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)
public void registerActivityLifecycleCallbacks(Application.ActivityLifecycleCallbacks callback) {
getApplication().registerActivityLifecycleCallbacks(callback);
}

}

然后修改manifest.xml将application指向com.youxiake.tinkerdemo.SampleApplication就行,开始会报错,build一下项目就好了

！！！指定 application 有三个注意的地方 ，如下这三个地方的application应该是一致的

这个案例中我们会将patch文件直接push到sdcard根目录，要从sdcard中读取补丁，所以要添加权限。

一定要注意：添加SDCard权限，如果你是6.x以上的系统，自己添加上授权代码（6.0权限问题），或者手动在手机设置页面打开SDCard读写权限。

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

搭建完成，开始进行测试了，在activity中新建如下代码。

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toast.makeText(this,"应用出错了....",Toast.LENGTH_SHORT).show();

//进行补丁的操作
TinkerInstaller.onReceiveUpgradePatch(this, Environment.getExternalStorageDirectory().getAbsolutePath()+"/patch");
}
}

先运行一个 应用出错的程序在手机上作为上线出bug的版本，运行图中的assembleDebug ，会在图一中生成debug文件。根据出错的apk的日期，去设置build.gredle 中 出错包的信息

将MainActivity中的 Toast 修改。(代表修改好的包)

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toast.makeText(this,"应用正常了....",Toast.LENGTH_SHORT).show();

//进行补丁的操作
TinkerInstaller.onReceiveUpgradePatch(this, Environment.getExternalStorageDirectory().getAbsolutePath()+"/patch");
}
}

运行tinkerPatchDebug，开始生成补丁



运行tinkerPatchDebug.png


（手机root过或者模拟器）通过adb push 补丁到和MainActivity中加载补丁的路径一致,补丁重命名 patch(随便在下怎么取名，一致就行)

TinkerInstaller.onReceiveUpgradePatch(this, Environment.getExternalStorageDirectory().getAbsolutePath()+"/patch");



adb push.png

最后结果 （第一次写，太唠叨了）
