android：一步步实现插件化与热更新（三）-原创手记-慕课网

热更新

热更新其实来源于插件化，如果你使用了上面的Small进行插件化开发，就可以直接进行插件化更新了！如果你没有使用插件化开发，你就可以只有热更新实现代码的热修复。

这里主要使用的是腾讯的Tinker。

在peoject的build中配置如下：

  dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'
        classpath "com.tencent.tinker:tinker-patch-gradle-plugin:${TINKER_VERSION}"
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }

TINKER_VERSION需要在gradle.properties中进行配置

TINKER_VERSION=1.7.7

接下来是配置app的build

这是我的，可以直接使用：

apply plugin: 'com.android.application'
//配置java版本
def javaVersion = JavaVersion.VERSION_1_7

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.2"
    compileOptions {
        sourceCompatibility javaVersion
        targetCompatibility javaVersion
    }
    //recommend
    dexOptions {
        jumboMode = true
    }
    signingConfigs {
        release {
            keyAlias 'tsou'
            keyPassword 'tsou123'
            storeFile file('D:/study/TinkerTest/app/keystore/tinkertest.jks')
            storePassword 'tsou123'
        }
        debug {
            keyAlias 'tsou'
            keyPassword 'tsou123'
            storeFile file('D:/study/TinkerTest/app/keystore/tinkertest.jks')
            storePassword 'tsou123'
        }
    }
    defaultConfig {
        applicationId "tsou.cn.tinkertest"
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"

        buildConfigField "String", "PLATFORM", "\"all\""
    }

    buildTypes {
        release {

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

            signingConfig signingConfigs.debug
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

                    preAssembleTask.doFirst {

                        project.tinkerPatch.oldApk = "${originOldPath}/${flavorName}/${project.name}-${flavorName}-debug.apk"
                        project.tinkerPatch.buildConfig.applyMapping = "${originOldPath}/${flavorName}/${project.name}-${flavorName}-debug-mapping.txt"

                    }

                }
            }
        }
    }
}

注意 修改buildConfigField

//客户端版本更新补丁
buildConfigField "String", "TINKER_ID", "\"2.0\""

如果更新客户端补丁需要修改，例如我把1.0改为2.0

配置application

/**
 * Created by Administrator on 2017/10/27 0027.
 */

@DefaultLifeCycle(application = ".SimpleTinkerInApplication",
        flags = ShareConstants.TINKER_ENABLE_ALL,
        loadVerifyFlag =true)
public class SimpleTinkerInApplicationLike extends ApplicationLike {
    public SimpleTinkerInApplicationLike (Application application, int tinkerFlags, boolean tinkerLoadVerifyFlag, long applicationStartElapsedTime, long applicationStartMillisTime, Intent tinkerResultIntent) {
        super(application, tinkerFlags, tinkerLoadVerifyFlag, applicationStartElapsedTime, applicationStartMillisTime, tinkerResultIntent);
    }

    @Override
    public void onBaseContextAttached(Context base) {
        super.onBaseContextAttached(base);
        MultiDex.install(base);
        TinkerInstaller.install(this);
    }

    @Override
    public void onCreate() {
        super.onCreate();
    }
}

SimpleTinkerInApplicationLike 并不是一个application
真正的application是@DefaultLifeCycle(application = “.SimpleTinkerInApplication”,这个
所以在androidmanifest中配置applica的name

 <application
        android:name=".SimpleTinkerInApplication"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>

                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
    </application>

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

运行你的项目使用release版本

效果如下：

图片描述

更改你的build.gradle

//老版本的文件所在的位置，大家也可以动态配置，不用每次都在这里修改
ext {
    tinkerEnabled = true

    tinkerOldApkPath = "${bakPath}/app-release-1201-13-55-26.apk"
    tinkerApplyMappingPath = "${bakPath}/app-release-1201-13-55-26-mapping.txt"
    tinkerApplyResourcePath = "${bakPath}/app-release-1201-13-55-26-R.txt"
    //only use for build all flavor, if not, just ignore this field
    tinkerBuildFlavorDirectory = "${bakPath}/app-1018-17-32-47"
}

更改代码：把“我的”改为“2222”
然后点击编译
生成目录如下
把patch_signed_7zip.apk放到手机根目录下，再执行更新
热更新代码如下：

public class MainActivity extends AppCompatActivity {

    private TextView tv;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        tv = (TextView) findViewById(R.id.tv);
        Button loadPath = (Button) findViewById(R.id.loadPath);
        tv.setText("2222");
        loadPath.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                requestPermi();
            }
        });
    }

    private void requestPermi() {
        if (ContextCompat.checkSelfPermission(MainActivity.this,
                Manifest.permission.READ_EXTERNAL_STORAGE)
                != PackageManager.PERMISSION_GRANTED) {
            // Should we show an explanation?
            if (ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this,
                    Manifest.permission.READ_EXTERNAL_STORAGE)) {

            } else {
                ActivityCompat.requestPermissions(MainActivity.this,
                        new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
                        100);
            }
        } else {
            //有权限直接加载apk
            loadApk();
        }
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        switch (requestCode) {
            case 100: {
                // If request is cancelled, the result arrays are empty.
                if (grantResults.length > 0
                        && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    //权限申请成功加载apk
                    loadApk();
                } else {
                }
                return;
            }
        }
    }

    public void loadApk() {
        String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/patch_signed_7zip.apk";
        File file = new File(path);
        if (file.exists()) {
            Toast.makeText(this, "补丁已经存在", Toast.LENGTH_SHORT).show();
            TinkerInstaller.onReceiveUpgradePatch(getApplicationContext(), path);
        } else {
            Toast.makeText(this, "补丁已经不存在", Toast.LENGTH_SHORT).show();
        }
    }
}
