在Android开发中，有很多地方都需要启动其他的程序，调起第三方应用（“QQ”、“微信”、“支付宝”、“高德地图”等），还有一些系统应用（“电话”、“短信”、“拍照”、“图库”等），下面一起来看看如何启动这些常用应用。

QQ

1. 第三方应用

1）通过包名启动

PackageManager packageManager = this.getPackageManager();
Intent intent= packageManager.getLaunchIntentForPackage("com.tencent.mobileqq");
startActivity(intent);

2）通过包名和类名启动

Intent intent = new Intent();  
ComponentName comp = new ComponentName("com.tencent.mobileqq", "com.tencent.mobileqq.activity.SplashActivity");  
intent.setComponent(comp);  
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);  
startActivity(intent);

2. 系统应用

1）从google搜索内容

Intent intent = new Intent();  
intent.setAction(Intent.ACTION_WEB_SEARCH);  
intent.putExtra(SearchManager.QUERY,"搜索内容")  
startActivity(intent);  

2）浏览网页

Uri uri = Uri.parse("http://www.google.com");  
Intent intent = new Intent(Intent.ACTION_VIEW,uri);  
startActivity(intent);  

3）显示地图

Uri uri = Uri.parse("geo:36.899533,66.036476");  
Intent intent = newIntent(Intent.Action_VIEW,uri);  
startActivity(intent);  

4）路径规划

Uri uri = Uri.parse("http://maps.google.com/maps?f=d&saddr=39.9 116.3&daddr=31.2 121.4");  
Intent intent = newIntent(Intent.ACTION_VIEW,URI);  
startActivity(intent);  

5）拨打电话

Uri uri = Uri.parse("tel:10086");  
Intent intent = new Intent(Intent.ACTION_DIAL,uri);    
startActivity(intent);  

6）发短信

Uri uri = Uri.parse("smsto:10086");     
Intent intent = new Intent(Intent.ACTION_SENDTO, uri);     
intent.putExtra("sms_body", "SMS Text");     
startActivity(intent);  

7）发送彩信

Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra("sms_body", "Hello");
Uri uri = Uri.parse("content://media/external/images/media/23");
intent.putExtra(Intent.EXTRA_STREAM, uri);
intent.setType("image/png");
startActivity(intent);

8）发送Email

Uri uri = Uri.parse("mailto:123456@qq.com");  
Intent intent = new Intent(Intent.ACTION_SENDTO, uri);  
startActivity(intent);  

9）播放多媒体

Intent intent = new Intent(Intent.ACTION_VIEW);  
Uri uri = Uri.parse("file:///sdcard/song.mp3");  
intent.setDataAndType(uri,"audio/mp3");  
startActivity(intent);

10）设置界面

Intent intent = new Intent(android.provider.Settings.ACTION_SETTINGS);
startActivity(intent);

11）拍照

 // 打开拍照程序
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, 1);

 // 取出照片数据
Bundle extras = intent.getExtras();
Bitmap bitmap = (Bitmap) extras.get("data");

12）选择图片

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(intent, 2);

13）打开录音机

Intent intent = new Intent(Media.RECORD_SOUND_ACTION);  
startActivity(intent); 

14）卸载软件

Uri uri = Uri.fromParts("package", strPackageName, null);     
Intent intent = new Intent(Intent.ACTION_DELETE, uri);     
startActivity(intent);  

15）安装软件

String fileName = Environment.getExternalStorageDirectory() + "/myApp.apk";   
Intent intent = new Intent(Intent.ACTION_VIEW);   
intent.setDataAndType(Uri.fromFile(new File(fileName)),
"application/vnd.android.package-archive");   
startActivity(intent);  

3. 场景应用

检查版本更新，跳转到腾讯应用宝进行下载更新

/** 跳转到腾讯应用宝下载软件 */
public static void goThirdApp() {
    if (isAvilible(this, "com.tencent.android.qqdownloader")) {// 市场存在      
        startAppStore(getApplicationContext(), "项目包名", "com.tencent.android.qqdownloader");
    } else {
        Uri uri = Uri.parse("http://a.app.qq.com/o/simple.jsp?pkgname=项目包名");
        Intent it = new Intent(Intent.ACTION_VIEW, uri);
        startActivity(it);
    }
}

/** 启动到app详情界面 */
public static void startAppStore(Context context, String appPkg, String marketPkg) {
     try {
            if (TextUtils.isEmpty(appPkg))return;
                Uri uri = Uri.parse("market://details?id=" + appPkg);
                Intent intent = new Intent(Intent.ACTION_VIEW, uri);
        
             if (!TextUtils.isEmpty(marketPkg)) {
                intent.setPackage(marketPkg);
             }
              intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
              context.startActivity(intent);               
    } catch (Exception e) {
        e.printStackTrace();               
    }      
}

/** 判断软件是否存在 */
public static boolean isAvilible(Context context, String packageName) {
    try {
        context.getPackageManager().getPackageInfo(packageName, 0);
        return true;
    } catch (NameNotFoundException e) {
        return false;
    }
}
