Tinker简介
Tinker是微信官方的Android热补丁解决方案，它支持动态下发代码、So库以及资源，让应用能够在不需要重新安装的情况下实现更新。
tinker官方介绍
使用步骤
1.在项目的build.gradle文件中，添加以下代码：
dependencies {
classpath "com.tencent.tinker:tinker-patch-gradle-plugin:${TINKER_VERSION}"
}
在gradle.properties文件中配置TINKER_VERSION：
TINKER_VERSION = 1.7.9
2.在app的build.gradle文件中，添加以下代码：
dependencies {
provided("com.tencent.tinker:tinker-android-anno:${TINKER_VERSION}")
compile("com.tencent.tinker:tinker-android-lib:${TINKER_VERSION}")
compile('com.android.support:multidex:1.0.1')
}
def gitSha() {
try {
String gitRev = 'git rev-parse --short HEAD'.execute(null, project.rootDir).text.trim()
if (gitRev == null) {
throw new GradleException("can't get git rev, you should add git to system path or just input test value, such as 'testTinkerId'")
}
return gitRev
} catch (Exception e) {
throw new GradleException("can't get git rev, you should add git to system path or just input test value, such as 'testTinkerId'")
}
}
def bakPath = file("${buildDir}/bakApk/")
ext {
//for some reason, you may want to ignore tinkerBuild, such as instant run debug build?
tinkerEnabled = true
//for normal build
//old apk file to build patch apk
tinkerOldApkPath = "${bakPath}/app-debug-1018-17-32-47.apk"
//proguard mapping file to build patch apk
tinkerApplyMappingPath = "${bakPath}/app-debug-1018-17-32-47-mapping.txt"
//resource R.txt to build patch apk, must input if there is resource changed
tinkerApplyResourcePath = "${bakPath}/app-debug-1018-17-32-47-R.txt"
//only use for build all flavor, if not, just ignore this field
tinkerBuildFlavorDirectory = "${bakPath}/app-1018-17-32-47"
}

return hasProperty("OLD_APK") ? OLD_APK : ext.tinkerOldApkPath

return hasProperty("TINKER_ID") ? TINKER_ID : gitSha()
}
def buildWithTinker() {
return hasProperty("TINKER_ENABLE") ? TINKER_ENABLE : ext.tinkerEnabled
}
def getTinkerBuildFlavorDirectory() {
return ext.tinkerBuildFlavorDirectory
}
if (buildWithTinker()) {

//use sample, let BaseBuildInfo unchangeable with tinker
"tinker.sample.android.app.BaseBuildInfo"

}

}

largeModSize = 100
}
packageConfig {
configField("patchMessage", "tinker is sample to use")
configField("platform", "all")
configField("patchVersion", "1.0")
}
//or you can add config filed outside, or get meta value from old apk

}
List flavors = new ArrayList<>();
project.android.productFlavors.each {flavor ->
flavors.add(flavor.name)
}
boolean hasFlavors = flavors.size() > 0
def date = new Date().format("MMdd-HH-mm-ss")
android.applicationVariants.all { variant ->
def taskName = variant.name
tasks.all {
if ("assemble${taskName.capitalize()}".equalsIgnoreCase(it.name)) {
it.doLast {
copy {
def fileNamePrefix = "${project.name}-${variant.baseName}"
def newFileNamePrefix = hasFlavors ? "${fileNamePrefix}" : "${fileNamePrefix}-${date}"
def destPath = hasFlavors ? file("${bakPath}/${project.name}-${date}/${variant.flavorName}") : bakPath
from variant.outputs.outputFile
into destPath
rename { String fileName ->
fileName.replace("${fileNamePrefix}.apk", "${newFileNamePrefix}.apk")
}
from "${buildDir}/outputs/mapping/${variant.dirName}/mapping.txt"
into destPath
rename { String fileName ->
fileName.replace("mapping.txt", "${newFileNamePrefix}-mapping.txt")
}
from "${buildDir}/intermediates/symbols/${variant.dirName}/R.txt"
into destPath
rename { String fileName ->
fileName.replace("R.txt", "${newFileNamePrefix}-R.txt")
}
}
}
}
}
}
project.afterEvaluate {
//sample use for build all flavor for one time
if (hasFlavors) {
task(tinkerPatchAllFlavorRelease) {
group = 'tinker'
def originOldPath = getTinkerBuildFlavorDirectory()
for (String flavor : flavors) {
def tinkerTask = tasks.getByName("tinkerPatch${flavor.capitalize()}Release")
dependsOn tinkerTask
def preAssembleTask = tasks.getByName("process${flavor.capitalize()}ReleaseManifest")
preAssembleTask.doFirst {
String flavorName = preAssembleTask.name.substring(7, 8).toLowerCase() + preAssembleTask.name.substring(8, preAssembleTask.name.length() - 15)
project.tinkerPatch.oldApk = "${originOldPath}/${flavorName}/${project.name}-${flavorName}-release.apk"
project.tinkerPatch.buildConfig.applyMapping = "${originOldPath}/${flavorName}/${project.name}-${flavorName}-release-mapping.txt"
project.tinkerPatch.buildConfig.applyResourceMapping = "${originOldPath}/${flavorName}/${project.name}-${flavorName}-release-R.txt"
}
}
}
task(tinkerPatchAllFlavorDebug) {
group = 'tinker'
def originOldPath = getTinkerBuildFlavorDirectory()
for (String flavor : flavors) {
def tinkerTask = tasks.getByName("tinkerPatch${flavor.capitalize()}Debug")
dependsOn tinkerTask
def preAssembleTask = tasks.getByName("process${flavor.capitalize()}DebugManifest")
preAssembleTask.doFirst {
String flavorName = preAssembleTask.name.substring(7, 8).toLowerCase() + preAssembleTask.name.substring(8, preAssembleTask.name.length() - 13)
project.tinkerPatch.oldApk = "${originOldPath}/${flavorName}/${project.name}-${flavorName}-debug.apk"
project.tinkerPatch.buildConfig.applyMapping = "${originOldPath}/${flavorName}/${project.name}-${flavorName}-debug-mapping.txt"
project.tinkerPatch.buildConfig.applyResourceMapping = "${originOldPath}/${flavorName}/${project.name}-${flavorName}-debug-R.txt"
}
}
}
}
}
}
注意：
- defaultConfig中配置multiDexEnabled true
- ignoreWarning = true而不是false
- tinkerId赋一个值或者使用versionName
3.创建MyApplicationLinke，代码如下：
@SuppressWarnings("unused")
@DefaultLifeCycle(application = "com.example.tinkerdemo.MyApplication",
flags = ShareConstants.TINKER_ENABLE_ALL,
loadVerifyFlag = false)
public class MyApplicationLinker extends DefaultApplicationLike {
public MyApplicationLinker(Application application, int tinkerFlags, boolean tinkerLoadVerifyFlag,
long applicationStartElapsedTime, long applicationStartMillisTime, Intent tinkerResultIntent) {
super(application, tinkerFlags, tinkerLoadVerifyFlag, applicationStartElapsedTime, applicationStartMillisTime, tinkerResultIntent);
}
@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);
// Tinker tinker = Tinker.with(getApplication());
}
}
在类的注解中有application = “com.example.tinkerdemo.MyApplication”，意思是帮你生成Application,注意包名。生成的MyApplication的位置如图：
4.修复部分的代码：
public class MainActivity extends AppCompatActivity {
private TextView mTextView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTextView = (TextView) findViewById(R.id.text);
mTextView.setText("这是有问题的APK");
//点击TextView,开始修复
mTextView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
//指定补丁包位置，加载补丁包信息；test为补丁包名称，可以定制
TinkerInstaller.onReceiveUpgradePatch(getApplicationContext(),
Environment.getExternalStorageDirectory().getAbsolutePath() + "/test");
}
});
}
}
5.运行打包后，生成如图所示的文件：
6.修改代码，修改app中build.gradle中老版本的信息，即将上图中bakApk中的apk的名称app-debug-0510-15-43-08复制给build.gradle中的tinkerOldApkPath = “${bakPath}/app-debug-0510-15-43-08.apk”
7.使用命令生成新的apk和差异包
在app的目录下，运行gradle tinkerPatchdebug命令。
在app/build/output/tinkerPath/目录下生成差异包，如图所示：
移动端通过后台下载差异包，然后在后台服务中修复。
