android判断快捷方式是否已经创建的方法

public boolean checkShortcut()

{

boolean isInstallShortcut = false ;

final ContentResolver cr =this.getContentResolver();

final String AUTHORITY = "com.android.launcher.settings";

final Uri CONTENT_URI = Uri.parse("content://" + AUTHORITY + "/favorites?notify=true");

Cursor c = cr.query(CONTENT_URI,new String[] {"title","iconResource" },"title=?",

new String[] {"ARecorder" }, null);//Arecorder表示应用名称,在这里检查应用程序名称

if(c!=null && c.getCount()>0){

isInstallShortcut = true ;

}

return isInstallShortcut ;

}
