Getting started

Add tinker-gradle-plugin as a dependency in your main

build.gradle
in the root of your project:
buildscript {
    dependencies {
        classpath ('com.tencent.tinker:tinker-patch-gradle-plugin:1.9.1')
    }
}

Then you need to "apply" the plugin and add dependencies by adding the following lines to your

app/build.gradle
.
dependencies {
    //optional, help to generate the final application
    provided('com.tencent.tinker:tinker-android-anno:1.9.1')
    //tinker's main Android lib
    compile('com.tencent.tinker:tinker-android-lib:1.9.1')
}
...
...
apply plugin: 'com.tencent.tinker.patch'

If your app has a class that subclasses android.app.Application, then you need to modify that class, and move all its implements to SampleApplicationLike rather than Application:

-public class YourApplication extends Application {
+public class SampleApplicationLike extends DefaultApplicationLike {

Now you should change your

Application
class, make it a subclass of TinkerApplication. As you can see from its API, it is an abstract class that does not have a default constructor, so you must define a no-arg constructor:
public class SampleApplication extends TinkerApplication {
    public SampleApplication() {
      super(
        //tinkerFlags, which types is supported
        //dex only, library only, all support
        ShareConstants.TINKER_ENABLE_ALL,
        // This is passed as a string so the shell application does not
        // have a binary dependency on your ApplicationLifeCycle class.
        "tinker.sample.android.app.SampleApplicationLike");
    }
}

Use

tinker-android-anno
to generate your
Application
is recommended, you just need to add an annotation for your SampleApplicationLike class
@DefaultLifeCycle(
application = "tinker.sample.android.app.SampleApplication",             //application name to generate
flags = ShareConstants.TINKER_ENABLE_ALL)                                //tinkerFlags above
public class SampleApplicationLike extends DefaultApplicationLike

How to install tinker? learn more at the sample SampleApplicationLike.

For proguard, we have already made the proguard config automatic, and tinker will also generate the multiDex keep proguard file for you.

For more tinker configurations, learn more at the sample app/build.gradle.

Ark Support

How to run tinker on the Ark?

building patch

Just use the following command:

buildconfig
bash build_patch_dexdiff.sh old=xxx new=xxx
*
old
indicates the absolute path of android apk(not compiled by Ark) with bugs *
new
indicates the absolute path of android apk(not compiled by Ark) with fixing

The patch file is packaged in APK.

compiling in Ark

TODO

At present it's compiled by Ark compiler team. The output patch is still packaged in APK format without signature.

packaging the patch

For tinker-cli, add the following lines to your

tinker_config.xml
. Otherwise, the default configure will be used.
xml

            // path of patch
         // name of patch

For gradle, add the following lines to your
app/build.gradle
. Otherwise, the default configure will be used.
gradle
ark {
   path = "arkHot"         // path of patch
   name = "patch.apk"      // name of patch
}
The patch is compiled by Ark and placed on the above path. all subsequent operations are same as tinker-cli or gradle.

The ultimated patch APK consists of two patch files:

  • classes.dex
    for android
  • patch.apk
    with so for Ark.
