如何判斷是否安裝此Apk

轉載:https://blog.csdn.net/bingsfsg/article/details/89246559

利用 PackageManager 類的方法 getPackageInfo來判斷,,分享給大家供大家參考

private boolean isAppInstalled(String uri){

PackageManager pm = getPackageManager();

boolean installed =false;

try{

pm.getPackageInfo(uri,PackageManager.GET_ACTIVITIES);

installed =true;

}catch(PackageManager.NameNotFoundException e){

installed =false;

}

return installed;

}

上面是寫好的方法,只要再call下就行

if(isAppInstalled("com.yourpackage.package")){

//app installed

}

else{

//app not installed

}
