weex-android 开发问题

本文转载自查看原文 2018-12-01 16:37 1994 weex

weex 打包android不能加载本地图片且不支持base64

官方文档虽然有说

Schemes
本地资源

Weex SDK 提供 local scheme 来访问打包在应用程序中的资源，此 scheme 无法在 H5 环境下使用。目前，开发者可以在 image 组件和字体文件中使用本地资源。

在 iOS 中，Weex 会在 bundle resources 中查找。例如，image 组件的 src 属性为 local:///app_icon'， Weex 会加载 bundle resouce 中名为 app_icon 的图像资源，而字体文件也以相同的方式工作。

在 Android 中，image 组件将从 drawable 资源文件夹加载，如 res/drawable-xxx。但加载字体文件是不同的，Android 框架无法从 res 加载字体文件，因此 SDK 将从 asserts 文件夹加载它。

但使用local加载图片时在ios下可以成功加载图片base64，android不能加载

解决方案：

用Android Studio打开.. ... weex-project-test/platforms/android,

修改... .../platforms/android/app/src/main/java/com/weex/app/extend/ImageAdapter.java

将图片放在... .../platforms/android/app/src/main/assets/images

package com.weex.app.extend;

import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.net.Uri;

    try {
      byte[]bitmapArray;
      bitmapArray= Base64.decode(string, Base64.DEFAULT);
      bitmap= BitmapFactory.decodeByteArray(bitmapArray, 0, bitmapArray.length);
    } catch (Exception e) {
      e.printStackTrace();
    }

    return bitmap;
  }
  @Override
  public void setImage(final String url, final ImageView view,
                       WXImageQuality quality, final WXImageStrategy strategy) {

        String temp = url;
        // base64 start
        if (url.startsWith("data")) {
          int index = url.indexOf(":");
          String tempUrl = url.substring(index + 1,url.length());
          Bitmap bitmap = stringtoBitmap(tempUrl);
          view.setImageBitmap(bitmap);
          return;

        // 加载本地图片 end
        if (view.getLayoutParams().width <= 0 || view.getLayoutParams().height <= 0) {
          return;
        }


        if(!TextUtils.isEmpty(strategy.placeHolder)){
          Picasso.Builder builder=new Picasso.Builder(WXEnvironment.getApplication());
          Picasso picasso=builder.build();
          picasso.load(Uri.parse(strategy.placeHolder)).into(view);

          view.setTag(strategy.placeHolder.hashCode(),picasso);
        }

        Picasso.with(WXEnvironment.getApplication())
                .load(temp)
                .transform(new BlurTransformation(strategy.blurRadius))
                .into(view, new Callback() {
                  @Override

                      strategy.getImageListener().onImageFinish(url,view,true,null);
                    }

                    if(!TextUtils.isEmpty(strategy.placeHolder)){
                      ((Picasso) view.getTag(strategy.placeHolder.hashCode())).cancelRequest(view);
                    }
                  }

                  @Override
                  public void onError() {
                    if(strategy.getImageListener()!=null){
                      strategy.getImageListener().onImageFinish(url,view,false,null);
                    }
                  }
                });
      }
    },0);
  }
}

tips: 使用weex框架中npm run android 和genymotion调试android时看不到效果，npm run pack:android打包后即可

android打包信息修改

... ... /platforms/android/build.gradle

android 字体文件

直接将字体文件拷到... .../platforms/android/app/src/main/assets 即可，引用方式同下ios引用字体代码片段

tips: 每次都要拷贝文件麻烦，可在package.json中添加命令在打包和开发时拷贝文件到该目录下，如

"copy:android": "mkdir -p platforms/android/app/src/main/assets/; cp -rf src/assets/fonts platforms/android/app/src/main/assets/; cp -rf src/assets/images platforms/android/app/src/main/assets/",
"pack:android": "npm run copy:android && npm run clean:android && weex build android",
"android": "npm run copy:android && weex run android",

解决：参考https://www.aliyun.com/zixun/wenji/1224263.html

Android的项目目录里是有两个build文件夹的,一个是:项目目录/app/build,另一个是:项目目录/build。

把两个build都删掉,然后重新编译运行即可。

注意:在提交代码的时候两个build是不应该提交的。

问题：安卓webview中的字体会随着系统字体改变大小

在../platforms/android/sdk/src/main/java/com/taobao/weex/ui/view/WXWebView.java 添加代码，

// 防止安卓手机放大webview中的字体
settings.setTextZoom(100);

问题：please select andriod sdk

android-webview cookie 同步问题

weex-android默认没有做http请求同步cookie到webview中，参考网上实现代码，如下：

这里是将weex的android的sdk下载并拷贝到了工程中，需要在.../platforms/android/app/build.gradle中配置

../platforms/android/settings.gradle中配置

include ':app', ':sdk'

在../platforms/android/sdk/src/main/java/com/taobao/weex/ui/view/WXWebView.java

View Code

版本号控制：

../platforms/android/app/build.gradle

VersionCode：对消费者不可见，仅用于应用市场、程序内部识别版本，判断新旧等用途。应用商店就会以这个[VersionCode]为准，来判断版本。安装包的[VersionCode]数字越大就越新。一般[VersionCode]都是一个正整数
VersionName：展示给消费者，消费者会通过它认知自己安装的版本

    defaultConfig {
        applicationId ""
        minSdkVersion project.appMinSdkVersion
        targetSdkVersion project.targetSdkVersion
        versionCode 2 
        versionName "1.0.8" // here
        ndk {
            abiFilters "x86"
            abiFilters "armeabi"
        }
    }

外部应用调起安卓app ：

参考：https://www.jianshu.com/p/8e13860cb6da

通过scheme跳转：.../platforms/android/sdk/src/main/AndroidManifest.xml中添加一个activity

　　　　　<!-- schema -->
        <activity
            android:name="com.weex.app.SchemeActivity"
            android:label="@string/app_name">
            <!-- 要想在别的App上能成功调起App，必须添加intent过滤器 -->
            <intent-filter>
                <!--协议部分，随便设置-->
                <!-- <data android:scheme="ydmisdiag" android:host="com.yiducloud.misdiag" android:path="/"/> -->
                <data android:scheme="ydmisdiag"/>
                <!--下面这几行也必须得设置-->
                <category android:name="android.intent.category.DEFAULT"/>
                <action android:name="android.intent.action.VIEW"/>
                <category android:name="android.intent.category.BROWSABLE"/>
            </intent-filter>
        </activity>

新建../platforms/android/app/src/main/java/com/weex/app/SchemeActivity.java

package com.weex.app;

import android.content.Intent;
import android.os.Bundle;
import android.widget.TextView;


public class SchemeActivity extends AbsWeexActivity {
  private static final String TAG = "SchemeActivity";
  private TextView schemeTv;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Intent intent = new Intent();
    intent.setClass(SchemeActivity.this, WXPageActivity.class);
    //intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    startActivity(intent);
  }
}

实现按返回键三次后退出应用：

新建../platforms/android/app/src/main/java/com/weex/app/StorageActivity.java , 用来存储实例activity

package com.weex.app;

import android.app.Activity;
import android.app.Application;

import java.util.LinkedList;
import java.util.List;

public class StorageActivity extends Application {
  private List<Activity> activityList = new LinkedList<Activity>();
  private static StorageActivity instance;
  private StorageActivity() {
  }

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

  //单例模式中获取唯一的StorageActivity实例
  public static StorageActivity getInstance() {
    if(null == instance) {
      instance = new StorageActivity();
    }
    return instance;
  }

  //添加Activity到容器中
  public void addActivity(Activity activity)  {
    activityList.add(activity);
  }

  //遍历所有Activity并finish
  public void exit() {
    for(Activity activity:activityList) {
      activity.finish();
    }
    activityList.clear();
  }
}

空包签名(背景：app上架oppo应用市场，提示已有相同包名，需要认领)

mac下查看jdk路径 /usr/libexec/java_home -V

安装jdk，方便起见，将oppo提供的OppoSignVerify.apk同签名文件放在同一个文件夹

执行

jarsigner -verbose -keystore [签名文件] -signedjar OppoSignVerify_signed.apk OppoSignVerify.apk [签名文件]
