Tinker已知問題

由于原理與系統限制，Tinker有以下已知問題：

Tinker不支持修改AndroidManifest.xml，Tinker不支持新增四大組件；
由于Google Play的開發者條款限制，不建議在GP渠道動態更新代碼；
在Android N上，補丁對應用啟動時間有輕微的影響；
不支持部分三星android-21機型，加載補丁時會主動拋出”TinkerRuntimeException:checkDexInstall failed”；
由于各個廠商的加固實現并不一致，在1.7.6以及之后的版本，tinker不再支持加固的動態更新；
對于資源替換，不支持修改remoteView。例如transition動畫，notification icon以及桌面圖標。

1.首先在項目的build中，集成tinker插件，如下所示(目前最新版是1.7.6)

先看結構圖，只有幾個類而已：

這里寫圖片描述

項目中的build集成

buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:2.2.3' classpath ('com.tencent.tinker:tinker-patch-gradle-plugin:1.7.6') // 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}

1.再將app的build中的關聯屬性添加進去，這些屬性都是經過測試過的，都有注釋顯示，如果自己需要其他屬性，可以自己去github上查看并集成，文章末尾會送上地址，ps：官方的集成特別麻煩，有時候一整天都有可能搞不定，根據自己的需求和情況來添加，末尾會送上demo

3.在清單文件中集成application和服務 ,name的application必須是.AMSKY，如果你添加不進去，或者是紅色的話，請先build一下，如果你已經有了自己的application，后面我會說怎么來集成，Service中做的操作是在你加載成功熱更新插件后，會提示你更新成功，并且這里做了鎖屏操作就會加載熱更新插件，繼續往下看。

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.tinker.demo.tinkerdemo"> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:supportsRtl="true" android:name=".AMSKY" android:theme="@style/AppTheme"> <service  android:name=".service.SampleResultService"  android:exported="false"/> <activity android:name=".MainActivity">  <intent-filter>  <action android:name="android.intent.action.MAIN" />  <category android:name="android.intent.category.LAUNCHER" />  </intent-filter> </activity> </application></manifest>

4.到這里就已經基本集成的差不多了，剩下的就是代碼里面的集成，首先是application，這里主要說如果是自已已經存在的application的時候改怎么操作，這個applicaiton可以說就是自己的一個application，只不過寫法，要這樣去寫，可以在onCreate中做自己的一些操作，只不過清單文件中，要寫AMSKY

@SuppressWarnings("unused")@DefaultLifeCycle(application = "com.tinker.demo.tinkerdemo.AMSKY",   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,Resources[] resources, ClassLoader[] classLoader, AssetManager[] assetManager) { super(application,tinkerFlags,tinkerLoadVerifyFlag,applicationStartElapsedTime,applicationStartMillisTime, tinkerResultIntent, resources, classLoader, assetManager); } /** * 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); //MultiDex必須在Tinker初始化之前 MultiDex.install(base); //這里就是初始化Tinker TinkerInstaller.install(this,new DefaultLoadReporter(getApplication()),new DefaultPatchReporter(getApplication()), new DefaultPatchListener(getApplication()),SampleResultService.class,new UpgradePatch()); Tinker tinker = Tinker.with(getApplication()); //這個只是一個Toast提示 Toast.makeText( getApplication(),"沒鳥用，就是Toast提示而已", Toast.LENGTH_SHORT).show(); } @Override public void onCreate() { super.onCreate(); //這里可以做自己的操作 } @TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH) public void registerActivityLifecycleCallbacks(Application.ActivityLifecycleCallbacks callback) { getApplication().registerActivityLifecycleCallbacks(callback); }}

5.這里就是在MainActivity中來加載熱更新文件，在點擊加載的時候，就直接鎖屏加載(不要刪除service)，當然退出app，下次進來也是可以加載的嗎，這里加載補丁插件的話，路徑可以自己設置，我是放在根目錄的debug文件夾當中的，并且我的補丁插件名字叫patch，可以自行更改。

public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } /** * 加載熱補丁插件 * @param v */ public void loadPatch(View v) { TinkerInstaller.onReceiveUpgradePatch(getApplicationContext(), "/sdcard/debug/patch.apk"); } /** * 殺死應用加載補丁 * @param v */ public void killApp(View v) { ShareTinkerInternals.killAllOtherProcess(getApplicationContext()); android.os.Process.killProcess(android.os.Process.myPid()); } @Override protected void onResume() { super.onResume(); Utils.setBackground(false); } @Override protected void onPause() { super.onPause(); Utils.setBackground(true); }}

6.Service文件

public class SampleResultService extends DefaultTinkerResultService { private static final String TAG = "Tinker.SampleResultService"; @Override public void onPatchResult(final PatchResult result) { if (result == null) {  TinkerLog.e(TAG, "SampleResultService received null result!!!!");  return; } TinkerLog.i(TAG, "SampleResultService receive result: %s", result.toString()); //first, we want to kill the recover process TinkerServiceInternals.killTinkerPatchServiceProcess(getApplicationContext()); Handler handler = new Handler(Looper.getMainLooper()); handler.post(new Runnable() {  @Override  public void run() {  if (result.isSuccess) {   Toast.makeText(getApplicationContext(), "patch success, please restart process", Toast.LENGTH_LONG).show();  } else {   Toast.makeText(getApplicationContext(), "patch fail, please check reason", Toast.LENGTH_LONG).show();  }  } }); // is success and newPatch, it is nice to delete the raw file, and restart at once // for old patch, you can't delete the patch file if (result.isSuccess) {  File rawFile = new File(result.rawPatchFilePath);  if (rawFile.exists()) {  TinkerLog.i(TAG, "save delete raw patch file");  SharePatchFileUtil.safeDeleteFile(rawFile);  }  //not like TinkerResultService, I want to restart just when I am at background!  //if you have not install tinker this moment, you can use TinkerApplicationHelper api  if (checkIfNeedKill(result)) {  if (Utils.isBackground()) {   TinkerLog.i(TAG, "it is in background, just restart process");   restartProcess();  } else {   //we can wait process at background, such as onAppBackground   //or we can restart when the screen off   TinkerLog.i(TAG, "tinker wait screen to restart process");   new ScreenState(getApplicationContext(), new ScreenState.IOnScreenOff() {   @Override   public void onScreenOff() {    restartProcess();   }   });  }  } else {  TinkerLog.i(TAG, "I have already install the newly patch version!");  } } } /** * you can restart your process through service or broadcast */ private void restartProcess() { TinkerLog.i(TAG, "app is background now, i can kill quietly"); //you can send service or broadcast intent to restart your process android.os.Process.killProcess(android.os.Process.myPid()); } static class ScreenState { interface IOnScreenOff {  void onScreenOff(); } ScreenState(Context context, final IOnScreenOff onScreenOffInterface) {  IntentFilter filter = new IntentFilter();  filter.addAction(Intent.ACTION_SCREEN_OFF);  context.registerReceiver(new BroadcastReceiver() {  @Override  public void onReceive(Context context, Intent in) {   String action = in == null ? "" : in.getAction();   TinkerLog.i(TAG, "ScreenReceiver action [%s] ", action);   if (Intent.ACTION_SCREEN_OFF.equals(action)) {   context.unregisterReceiver(this);   if (onScreenOffInterface != null) {    onScreenOffInterface.onScreenOff();   }   }  }  }, filter); } }}

7.Utils文件

public class Utils { /** * the error code define by myself * should after {@code ShareConstants.ERROR_PATCH_INSERVICE */ public static final int ERROR_PATCH_GOOGLEPLAY_CHANNEL = -5; public static final int ERROR_PATCH_ROM_SPACE  = -6; public static final int ERROR_PATCH_MEMORY_LIMIT  = -7; public static final int ERROR_PATCH_ALREADY_APPLY  = -8; public static final int ERROR_PATCH_CRASH_LIMIT  = -9; public static final int ERROR_PATCH_RETRY_COUNT_LIMIT = -10; public static final int ERROR_PATCH_CONDITION_NOT_SATISFIED = -11; public static final String PLATFORM = "platform"; public static final int MIN_MEMORY_HEAP_SIZE = 45; private static boolean background = false; public static boolean isGooglePlay() { return false; } public static boolean isBackground() { return background; } public static void setBackground(boolean back) { background = back; } public static int checkForPatchRecover(long roomSize, int maxMemory) { if (Utils.isGooglePlay()) {  return Utils.ERROR_PATCH_GOOGLEPLAY_CHANNEL; } if (maxMemory < MIN_MEMORY_HEAP_SIZE) {  return Utils.ERROR_PATCH_MEMORY_LIMIT; } //or you can mention user to clean their rom space! if (!checkRomSpaceEnough(roomSize)) {  return Utils.ERROR_PATCH_ROM_SPACE; } return ShareConstants.ERROR_PATCH_OK; } public static boolean isXposedExists(Throwable thr) { StackTraceElement[] stackTraces = thr.getStackTrace(); for (StackTraceElement stackTrace : stackTraces) {  final String clazzName = stackTrace.getClassName();  if (clazzName != null && clazzName.contains("de.robv.android.xposed.XposedBridge")) {  return true;  } } return false; } @Deprecated public static boolean checkRomSpaceEnough(long limitSize) { long allSize; long availableSize = 0; try {  File data = Environment.getDataDirectory();  StatFs sf = new StatFs(data.getPath());  availableSize = (long) sf.getAvailableBlocks() * (long) sf.getBlockSize();  allSize = (long) sf.getBlockCount() * (long) sf.getBlockSize(); } catch (Exception e) {  allSize = 0; } if (allSize != 0 && availableSize > limitSize) {  return true; } return false; } public static String getExceptionCauseString(final Throwable ex) { final ByteArrayOutputStream bos = new ByteArrayOutputStream(); final PrintStream ps = new PrintStream(bos); try {  // print directly  Throwable t = ex;  while (t.getCause() != null) {  t = t.getCause();  }  t.printStackTrace(ps);  return toVisualString(bos.toString()); } finally {  try {  bos.close();  } catch (IOException e) {  e.printStackTrace();  } } } private static String toVisualString(String src) { boolean cutFlg = false; if (null == src) {  return null; } char[] chr = src.toCharArray(); if (null == chr) {  return null; } int i = 0; for (; i < chr.length; i++) {  if (chr[i] > 127) {  chr[i] = 0;  cutFlg = true;  break;  } } if (cutFlg) {  return new String(chr, 0, i); } else {  return src; } }}

到這里就已經集成完畢，下面來說下使用的方法

這是有bug的版本，我們測試就使用assembleDebug來測試，注意沒點擊assembleDebug之前，build文件夾里面是沒有bakApk文件夾的
