  • 防止CLASS_ISPREVERIFIED,补丁制作

原理请看这篇文字,这篇文章介绍的“实现javassist动态代码注入”使用Groovy开发的demo中代码注入,要一个个填写注入,本人写了一个transformClasses.jar,实现批量代码注入,用法如下:

java -jar transformClasses.jar classPath libPath ignore
classPath:项目编译class所在目录
libPath:项目运行的依赖class路径,包括AntilazyLoad.class所在目录(注入代码必须用到)
ignore:忽略注入代码的类,如: *.APP   packageName.*  packageName.className
以上参数均可用;表示多个


//在build.gradle插入以下代码
//gradle1.4以下使用这段
task('processWithJavassist') << {
    println '-----------開始往class插入代碼-----------------'

    String classPath = project(':app').buildDir.absolutePath   '/intermediates/classes/debug'//项目编译class所在目录
    String libPath = "$rootDir/transformClasses;$rootDir/transformClasses/androidClass" //AntilazyLoad.class及android.jar解压后的class所在目录
    String ignore = "*.App;*.BuildConfig;online.magicbox.bugfix.*;online.magicbox.app.R.*;cn.jpush.*"
    println classPath
    println libPath
    println ignore

    javaexec {
        classpath "$rootDir/transformClasses/transformClasses.jar"
        main = 'cn.georgeyang.TransformClasses'
        args classPath,libPath,ignore
    }
}

//gradle1.5及以上使用这段:
gradle.taskGraph.beforeTask { Task task ->
    println "beforeTask:"   task.name   ","   task.group   ","   task.getProject().name
        if (task.name.equals("preBuild") && task.getProject().name.equals("app")) {
            String rootPath = project.rootDir.absolutePath
            String jarPath = rootPath   "/transformClasses/transformClasses.jar"
            String classPath = project.buildDir.absolutePath   '/intermediates/classes/debug'//项目编译class所在目录
            String libPath = rootPath   "/transformClasses;"    rootPath  "/transformClasses/androidClass" //AntilazyLoad.class及android.jar解压后的class所在目录
            String ignore = "*.App;*.BuildConfig;online.magicbox.bugfix.*;online.magicbox.app.R.*;cn.jpush.*"
            project.javaexec {
                classpath jarPath
                main = 'cn.georgeyang.TransformClasses'
                args classPath,libPath,ignore
            }
    }
}

//gradle1.5及以上,自定义gradlePlugIn写法:
apply plugin: CodeInsert
class CodeInsert implements Plugin<Project> {
    @Override
    void apply(Project project) {
        project.afterEvaluate {
            project.android.applicationVariants.each { variant ->
                def dexTaskName = "transformClassesWithDexFor${variant.name.capitalize()}"
                def dexTask = project.tasks.findByName(dexTaskName)
                if (dexTask) {
                    String rootPath = project.rootDir.absolutePath
                    String jarPath = rootPath   "/transformClasses/transformClasses.jar"
                    String classPath = project.buildDir.absolutePath   '/intermediates/classes/debug'//项目编译class所在目录
                    String libPath = rootPath   "/transformClasses;"    rootPath  "/transformClasses/androidClass" //AntilazyLoad.class及android.jar解压后的class所在目录
                    String ignore = "*.App;*.BuildConfig;online.magicbox.bugfix.*;online.magicbox.app.R.*;cn.jpush.*"
                    project.javaexec {
                        classpath jarPath
                        main = 'cn.georgeyang.TransformClasses'
                        args classPath,libPath,ignore
                    }
                }
            }
        }
    }
}

进过transformClasses.jar处理后,如何知道哪些类可以热修复?

查看gradle console,会有如下结果

成功插入AntilazyLoad代码的会显示:
  transform success:	***.class

失败会显示:
# transform fail:	 fail reasion - ***.class

R文件不能热修复,所以被忽略:
# ingroe resoure:   ***.class

指定忽略的会显示:
~ transform ignore by match:  ignoreType - ***.class

只有transform success的类才能热更新

插件

加载插件代码原理: 重写classloder
加载插件View实现:参考

插件开发依赖devlibrary项目

  • 定义一个Slice(类似activity的类,用于pluginActivity加载)
public class MainSlice extends Slice {
...
}

加载这个Slice:

public class MainActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        PluginActivity.init("cn.georgeyang.flashlight","magicbox","2");//包名,定义的scheme,版本号
        Intent intent = PluginActivity.buildIntent(this,MainSlice.class);
        startActivity(intent);

        finish();
    }
}
  • 插件中要使用fragment
public class FileFragment extends PluginFragment {
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        view = getPluginLayoutInflater().inflate(R.layout.fragment_file,null);
    }
    //getPluginContext().getResources().getStringArray(R.array.item}
  • 调用其他插件的图片选择器
Intent picker = PluginActivity.buildIntent(getActivity(),"online.magicbox.desktop","ImageSelectorSlice","1");
picker.putExtra("select_count_mode",0);
getActivity().startActivityForResult(picker,100);
  • Slice中的权限申请(fragment也一样):
requestPermission(123,Manifest.permission.CAMERA);

    @Override
    public void onPermissionGiven(int code,String permission) {
        super.onPermissionGiven(code,permission);
        if (code == 123) {
            Intent scan = PluginActivity.buildIntent(getActivity(), CaptureSlice2.class);
            getActivity().startActivityForResult(scan, 50);
        }
    }

本项目中插件的缺点:

  • 目前没有写service,receiver的支持
  • Slice继承的是Context,而不是activity,很多方法要谨慎使用
  • 大量使用反射调用app宿主程序,效率减低

使用方法: 将app-build-outputsd的app-debug.apk提取classes.dex文件,将这个文件压缩,生成一个只有代码没有资源的zip包,这个包便是补丁包,

同一个项目下生成的补丁,兼容不同的签名,debug生成的补丁也可以给release版本打补丁。
