Android 安装软件后执行“OPEN”引起的Intent血案（系统BUG）

打开程序的入口有很多个：

 

shell 命令行运行；

Launcher待机界面执行；

状态通知栏运行；

桌面快捷方式运行；

软件中调用运行；

 

安装软件后执行“OPEN”运行！

 

前面几项，调用程序的代码如下（参考：com.android.Launcher/.Launcher.java）：

 

Intent intent = new Intent(this, TestActivity.class);intent.setAction(Intent.ACTION_MAIN);intent.addCategory(Intent.CATEGORY_LAUNCHER);intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);intent.addFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);this.startActivity(intent); 

 

而安装软件后，点击“Open”调用的代码如下（参考：com.android.packageinstaller/.InstallAppDone.java）：

 

Intent intent = new Intent(this, TestActivity.class);this.startActivity(intent); 

 

如果用户安装软件后立刻执行“Open”，运行程序后，按HOME键返回到后台，然后再通过别的几种方法运行程序，则会再起一个MAIN程序。这是因为Intent的处理机制是，先比较Activity，再比较Action、Flag、bnds。。。，前后两张方式的Action不一样，一个有LAUNCHER ACTION，一个没有，所以会认为是启动两个不同的INTENT。

 

目前只想到一个简单的处理方式：

 

程序入口MAIN程序：SplashActivity.java

程序原入口程序：LoginActivity.java

 

启动程序后，在状态通知栏上添加快捷通知，代码如下：

 

package org.anymobile.test;import android.app.Activity;import android.app.Notification;import android.app.NotificationManager;import android.app.PendingIntent;import android.content.ComponentName;import android.content.Context;import android.content.Intent;import android.os.Bundle;public class SplashActivity extends Activity{@Overrideprotected void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);this.showNotification(this.getBaseContext(), -1, "Test is Running!", "Test Start Up!");Intent intent = this.getIntent();if (intent.hasCategory(Intent.CATEGORY_LAUNCHER)){intent = new Intent(this, TestActivity.class);this.startActivity(intent);}else{intent = new Intent();ComponentName componentName = new ComponentName(this, SplashActivity.class);intent.setComponent(componentName);//intent = new Intent(this, SplashActivity.class);intent.setAction(Intent.ACTION_MAIN);intent.addCategory(Intent.CATEGORY_LAUNCHER);intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);intent.addFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);this.startActivity(intent);}this.finish();} public void showNotification(Context context,int iResIcon,String sNotifybar,String sNofitymsg) { // look up the notification manager service NotificationManager nm = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE); // The details of our fake message CharSequence from = "Test"; CharSequence message = sNofitymsg; Intent intent = new Intent();ComponentName componentName = new ComponentName(context, TestActivity.class);intent.setComponent(componentName);intent.setAction(Intent.ACTION_MAIN);intent.addCategory(Intent.CATEGORY_LAUNCHER);intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);intent.addFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED); PendingIntent contentIntent = PendingIntent.getActivity(context, 0, intent, 0); Notification notification = new Notification(iResIcon,sNotifybar, System.currentTimeMillis()); notification.flags = notification.flags | Notification.FLAG_ONGOING_EVENT; notification.defaults = /*Notification.DEFAULT_SOUND|*/Notification.DEFAULT_LIGHTS; notification.setLatestEventInfo(context, from, message, contentIntent); nm.notify(R.string.app_name, notification); }@Overrideprotected void onStart(){// TODO Auto-generated method stubsuper.onStart();}@Overrideprotected void onResume(){// TODO Auto-generated method stubsuper.onResume();}@Overrideprotected void onStop(){// TODO Auto-generated method stubsuper.onStop();}@Overrideprotected void onDestroy(){// TODO Auto-generated method stubsuper.onDestroy();}} 

 

package org.anymobile.test;import android.app.Activity;//import android.content.ComponentName;import android.content.Intent;import android.graphics.LightingColorFilter;import android.os.Bundle;import android.view.Menu;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;public class TestActivity extends Activity{private static final int ADD_ID = 0;private static final int DEL_ID = 1; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) {Intent intent = this.getIntent();if (! intent.hasCategory(Intent.CATEGORY_LAUNCHER)){this.getIntent().addCategory(Intent.CATEGORY_LAUNCHER);}this.getWindow().addFlags(CONTEXT_IGNORE_SECURITY); super.onCreate(savedInstanceState); setContentView(R.layout.main); Button button = (Button) this.findViewById(R.id.btn_menu); button.setOnClickListener(new OnClickListener() { public void onClick(View v) {// TestActivity.this.openOptionsMenu(); // String packName = "com.longcheer.imm";// String className = packName + ".activitys.LoginActivity";// // Intent intent = new Intent();// ComponentName componentName = new ComponentName(packName, className);// intent.setComponent(componentName);// // intent.setAction("android.intent.action.MAIN");// intent.addCategory("android.intent.category.LAUNCHER");// intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);// intent.addFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);// // TestActivity.this.startActivity(intent); Intent intent = new Intent(TestActivity.this, Test2Activity.class); TestActivity.this.startActivity(intent); TestActivity.this.finish(); } });// button.getBackground().setColorFilter(0xFFFF0000, PorterDuff.Mode.MULTIPLY); button.getBackground().setColorFilter(new LightingColorFilter(0xFFFFFFFF, 0xFFAA0000)); }@Overrideprotected void onRestoreInstanceState(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onRestoreInstanceState(savedInstanceState);}@Overrideprotected void onSaveInstanceState(Bundle outState) {// TODO Auto-generated method stubsuper.onSaveInstanceState(outState);}@Overridepublic boolean onCreateOptionsMenu(Menu menu){menu.add(0, ADD_ID, 0, "ADD");menu.add(0, DEL_ID, 0, "DEL");return super.onCreateOptionsMenu(menu);} } 

 

package org.anymobile.test;import android.app.Activity;import android.content.ComponentName;import android.content.Context;import android.content.Intent;import android.graphics.LightingColorFilter;import android.os.Bundle;import android.text.ClipboardManager;import android.view.Menu;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;public class Test2Activity extends Activity{private static final int ADD_ID = 0;private static final int DEL_ID = 1; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ClipboardManager clip = (ClipboardManager)getSystemService(Context.CLIPBOARD_SERVICE); Button button = (Button) this.findViewById(R.id.btn_menu); button.setText("22222222"); button.setOnClickListener(new OnClickListener() { public void onClick(View v) { Test2Activity.this.openOptionsMenu();// String packName = "com.longcheer.imm";// String className = packName + ".activitys.LoginActivity";// // Intent intent = new Intent();// ComponentName componentName = new ComponentName(packName, className);// intent.setComponent(componentName);// // intent.setAction("android.intent.action.MAIN");// intent.addCategory("android.intent.category.LAUNCHER");// intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);// intent.addFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);// // Test2Activity.this.startActivity(intent); } });// button.getBackground().setColorFilter(0xFFFF0000, PorterDuff.Mode.MULTIPLY); button.getBackground().setColorFilter(new LightingColorFilter(0xFFFFFFFF, 0xFFAA0000)); }@Overridepublic boolean onCreateOptionsMenu(Menu menu){menu.add(0, ADD_ID, 0, "ADD2");menu.add(0, DEL_ID, 0, "DEL2");return super.onCreateOptionsMenu(menu);} } 

 

测试流程：

 

a、软件本地安装；

b、安装后执行“Open”；

c、运行软件会从SplashActivity添加NOTICIFICATION TestActivity；

d、跳转至SplashActivity（附带LAUNCHER ACTION）；

e、再跳转至TestActivity；

f、点击BUTTON，跳转至Test2Activity；

g、下拉状态通知栏，点击程序通知，可以正常运行程序。

 

TODO: 安装软件后执行OPEN后，从待机界面运行程序，还是会启动两个一样的ACTIVITY，这个问题没有解决！：（
