Android开发之第三方跳转
接收端逻辑
1.首先添加action
如下所示 代码：
2.onCreate方法增加逻辑
在启动activity（此处为StartActivity）的onCreate方法中super.onCreate之前添加跳转逻辑处理。类似下约：
protected void onCreate(Bundle savedInstanceState) {
LogHelper.releaseLog("StartActivity", "StartActivity init");
// add Third party jump
Intent intent = getIntent();
if(null != intent){
startThirdJump(intent,savedInstanceState);
}
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_start);}3.跳转原理及方法处理
跳转原理即：第三方跳转入口处（请求发送端），提供跳转页面ID，以及跳转参数信息Map。在接受跳转的apk（请求接收端）中处理。根据相应的页面ID和参数信息Map启动相应的页面即可。
startThirdJump方法：
private void startThirdJump(Intent intent, Bundle savedInstanceState){
Bundle extraBundle = intent.getExtras();
if(null != extraBundle && extraBundle.containsKey("Data")){
String extraString = extraBundle.getString("Data");
LogHelper.releaseLog("StartActivity", "extraString:"+extraString);
parseExtraJump(extraString);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_start);
setExtraJump();
}
}private void parseExtraJump(String info){
if(mExtraJumpParser==null){
mExtraJumpParser = new ExtraJumpParser();
}
mExtraJumpParser.mParseData = info;
mExtraJumpParser.run();
}
ExtraJumpParser类参考（部分代码如下：）
public class ExtraJumpParser extends BaseParser{
private KEY_PAGEID mPageID = null;
private Map mJumpMap = null;
public KEY_PAGEID getExtraPageID(){
return mPageID;
}
@Override
public void run()
{
parseExtraJump();
}
private void parseExtraJump(){
mPageID = null;
String[] paramsStrings = mParseData.split("&");
String[] params;
mJumpMap = new HashMap();
for(int i=0;i getJumpParam(){
return mJumpMap;
}
}
setExtraJump方法：执行跳转（代码参考）
private void setExtraJump() {
KEY_PAGEID pageId = mExtraJumpParser.getExtraPageID();
if (pageId != null) {
Map param = mExtraJumpParser.getJumpParam();
if (pageId == KEY_PAGEID.PAGE_PLAY) {
PLAY_DATA playData = new PLAY_DATA();
playData.sid = (String) param.get(KEY_PAGEDATA.SID);
playData.contentType = (String) param.get(KEY_PAGEDATA.CONTENTTYPE);
playData.supplyType = (String) param.get(KEY_PAGEDATA.SUPPLYTYPE);
param.put(KEY_PAGEDATA.PLAYDATA, playData);
StaticFunction.getPageHelper().jumpPage(KEY_PAGEID.PAGE_PLAY,param);
}
else {
StaticFunction.getPageHelper().jumpPage(pageId, param);
}
}
StaticFunction.getPageHelper().finishPage(null);
} public class PageHelper {
private Map> mActivityInfo = new HashMap>();
private ArrayList mActivityList = new ArrayList();
private ArrayList mPageIDList = new ArrayList();

} 注意：一定是在startActivity中做的跳转处理，其他的activity可以从PageHelper中的getPageInfo获取相应的需要信息。
请求发送端逻辑
可以从第三方的APP跳转到另一个APP中的某个特殊页面。
方法参考：
public void jumpExtraAPP(String action, String page) {
try {
String pageInfoString = page;
Intent testIntent = new Intent();
testIntent.setAction(action);
Log.i("info", pageInfoString);
testIntent.putExtra("Data", pageInfoString);
testIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK
| Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(testIntent);
} catch (Exception e) {
e.printStackTrace();
}
}
上面是根据action实现跳转，还有就是根据包名跳转。
public static void JumpHomeApp(String packageName) {
try {
Intent intent =LauncherApplication.sObj.getPackageManager().getLaunchIntentForPackage(packageName);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK |Intent.FLAG_ACTIVITY_NEW_TASK);
LauncherApplication.sObj.startActivity(intent);
setJumpAnim();
} catch (Exception e) {
e.printStackTrace();
}
}
public static void JumpHomeApp(String packageName) {
try {
Intent intent =LauncherApplication.sObj.getPackageManager().getLaunchIntentForPackage(packageName);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK |Intent.FLAG_ACTIVITY_NEW_TASK);
LauncherApplication.sObj.startActivity(intent);
setJumpAnim();
} catch (Exception e) {
e.printStackTrace();
}
}
-----------------------------------------------------------------
另一种跳转，使用ComponentName实现 ：
跳转至登录页
public void jumpToLoginActivity( ){
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
ComponentName cn = new ComponentName("com.mcptt", "com.mcptt.LoginActivity");
intent.setComponent(cn);
String usernumber = "mcptt_usernumber";
String password = "mcptt_password";
String server_domain = "mcptt_service_domain";
String server_ip = "mcptt_service_ip";
String server_port = "mcptt_service_port";
String login_type = "key_login_type";
String login_auto = "key_login_auto";
Bundle bundle = new Bundle();
bundle.putInt(login_type, 0);// 0 域名登录，1 ip登录，互斥
bundle.putString(server_domain, "real.caltta.com.cn:80");
//bundle.putString(server_ip, "114.55.250.9");
//bundle.putInt(server_port, 13001);
bundle.putString(usernumber, "20025201001");
bundle.putString(password, "111111");
bundle.putBoolean(login_auto, true);
intent.putExtras(bundle);
try {
startActivity(intent);
} catch (Exception e) {
e.printStackTrace();
}
} 可能很啰嗦，也可能根本没说明白，但是要理解这也是一种协议，这边怎么发，那边怎么收，要约定好。
