所以我完成了测试APK我在Android Studio中制作的内容并试图在我的手机上安装应用程序时出现错误:“解析包时出现问题”我甚至尝试过正常构建APK我尝试过未签名/已签名的APK,仍然无法使用。以下是我用来制作应用程序的所有代码:

我也使用了本教程:https://youtu.be/92f4c2vHrPg?list=FL-enUuEaX-zrgjvaCOrqRSQ

package com.example.sami.kartta;

import android.support.v4.app.FragmentActivity;
import android.os.Bundle;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

    private GoogleMap mMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
        // Obtain the SupportMapFragment and get notified when the map is ready to be used.
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);
    }


    /**
     * Manipulates the map once available.
     * This callback is triggered when the map is ready to be used.
     * This is where we can add markers or lines, add listeners or move the camera. In this case,
     * we just add a marker near Sydney, Australia.
     * If Google Play services is not installed on the device, the user will be prompted to install
     * it inside the SupportMapFragment. This method will only be triggered once the user has
     * installed Google Play services and returned to the app.
     */
    @Override
    public void onMapReady(GoogleMap googleMap) {
        mMap = googleMap;

        // Add a marker in Sydney and move the camera
        LatLng sydney = new LatLng(-34, 151);
        mMap.addMarker(new MarkerOptions().position(new LatLng(60.167469, 24.930913)).title("Helsinki"));
        mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
    }

TODO: Before you run your application, you need a Google Maps API key.

To get one, follow this link, follow the directions and press "Create" at the end:

https://console.developers.google.com/flows/enableapi?apiid=maps_android_backend&keyType=CLIENT_SIDE_ANDROID&r=5A:5C:C8:D8:90:F8:81:95:79:34:0B:C7:08:57:6A:32:71:72:26:68%3Bcom.example.sami.kartta

You can also add your credentials to an existing key, using these values:

Package name:
5A:5C:C8:D8:90:F8:81:95:79:34:0B:C7:08:57:6A:32:71:72:26:68

SHA-1 certificate fingerprint:
5A:5C:C8:D8:90:F8:81:95:79:34:0B:C7:08:57:6A:32:71:72:26:68

Alternatively, follow the directions here:
https://developers.google.com/maps/documentation/android/start#get-key

Once you have your key (it starts with "AIza"), replace the "google_maps_key"
string in this file.

<string name="google_maps_key" templateMergeStrategy="preserve" translatable="false">YOUR_KEY_HERE</string>
