Android业务组件化之URL Scheme实例

一、发送参数应用

这里打开第三方应用(第三方支持并且接收参数)，
参数说明：
packageName 第三方包名 ，account，verifyTime ，sign ，传递给第三方的参数

public void openApp(String packageName, String account,String verifyTime ,String sign) {
        PackageManager packageManager = mContext.getPackageManager();
        PackageInfo pi = null;
        try {
            pi = packageManager.getPackageInfo(packageName, 0);
        } catch (PackageManager.NameNotFoundException e) {
            e.printStackTrace();
        }

        Intent resolveIntent = new Intent(Intent.ACTION_MAIN, null);
        resolveIntent.addCategory(Intent.CATEGORY_LAUNCHER);
        resolveIntent.setPackage(pi.packageName);
        List<ResolveInfo> apps = packageManager.queryIntentActivities(resolveIntent, 0);
 
        ResolveInfo ri = apps.iterator().next();

        if (ri != null) {
            String className = ri.activityInfo.name;
            String path = "comcpscapps://open/appInfo?account_name=" + account+"&verify_time="+verifyTime+"&sign="+sign;
            Uri uri = Uri.parse(path);
            Intent intent = new Intent(Intent.ACTION_VIEW, uri);
            intent.addCategory(Intent.CATEGORY_LAUNCHER);
            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            ComponentName cn = new ComponentName(packageName, className);
            intent.setComponent(cn);
            mContext.startActivity(intent);
        }
    }

二、接收参数的App
1.在AndroidManifest.xml中，在app入口的activity 中添加 android:exported="true" 属性

<intent-filter>
    <data android:scheme="comcpscapps" android:host="open" android:path="/appInfo"/>
    <category android:name="android.intent.category.DEFAULT" />
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.BROWSABLE" />
 </intent-filter>

如下图所示：

2在入口activity中获取传递过来的参数

       Uri uri = getIntent().getData();
        if (uri != null) {
            String url = uri.toString();  // 完整的url信息
            String scheme = uri.getScheme(); // scheme部分
            String host = uri.getHost(); // host部分
            String path = uri.getPath();// 访问路劲
            //获取指定参数值
            String account = uri.getQueryParameter("account_name");
            String verifyTime = uri.getQueryParameter("verify_time");
            String sign = uri.getQueryParameter("sign");
            test.setText("account:" + account + "\r\n" + "verifyTime:" + verifyTime + "\r\n" + "sign:" + sign);
        } else {
            test.setText("-2");
        }

3.接收参数结果

1）成功

2 ) 第三方不是工作应用App或者接收失败

不是工作应用

接收失败，默认-2
