Android 安裝程序(APK)後並啓動程序(APK)
Intent i = new Intent(Intent.ACTION_VIEW);
i.setDataAndType(Uri.parse("file://" + apkfile),"application/vnd.android.package-archive");

finish();// 沒寫finish的話不會彈出完成和打開 /* 安裝apk */
public static void installApk(Context context, String fileName) {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setDataAndType(Uri.parse("file://" + fileName),"application/vnd.android.package-archive");
context.startActivity(intent);
}
/* 卸載apk */
public static void uninstallApk(Context context, String packageName) {
Uri uri = Uri.parse("package:" + packageName);
Intent intent = new Intent(Intent.ACTION_DELETE, uri);
