自从上次对AIDE更新以来,我一直在使用Google Play服务时遇到问题。我发现,仅将依赖关系添加到我的构建gradle文件中将导致发生运行时错误,并且没有它我的应用程序将正常运行。我只是想在pageviewer中使用google map,但是我不能仅仅添加依赖项。
这是我的build.gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.0"
defaultConfig {
applicationId "com.Smartz.CoPilot"
minSdkVersion 14
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
//compile 'com.google.android.gms:play-services-maps:+'
compile fileTree(dir: 'libs', include: ['*.jar'])
}
在未注释掉依赖项的情况下,出现以下运行时错误: java.lang.RuntimeException:无法实例化活动ComponentInfo {com.Smartz.CoPilot / com.Smartz.CoPilot.PageViewActivity}:java.lang.ClassNotFoundException:在路径中找不到类“ com.Smartz.CoPilot.PageViewActivity”。 DexPathList [[zip文件“ /data/app/com.Smartz.CoPilot-1/base.apk"],nativeLibraryDirectories=[/data/app/com.Smartz.CoPilot-1/lib/arm、/vendor/lib, / system / lib]]
这是我的清单:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.Smartz.CoPilot" >
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme"
android:resizeableActivity = "true">
<activity
android:name=".PageViewActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
这是我的活动代码:
package com.Smartz.CoPilot;
import java.util.ArrayList;
import java.util.List;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
public class PageViewActivity extends FragmentActivity {
MyPageAdapter pageAdapter;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_page_view);
List<Fragment> fragments = getFragments();
pageAdapter = new MyPageAdapter(getSupportFragmentManager(), fragments);
ViewPager pager = findViewById(R.id.viewpager);
pager.setAdapter(pageAdapter);
}
private List<Fragment> getFragments(){
List<Fragment> fList = new ArrayList<Fragment>();
fList.add(RedFragment.newInstance("Red Fragment"));
//fList.add(MyFragment.newInstance("Fragment 2"));
//fList.add(MyFragment.newInstance("Fragment 3"));
return fList;
}
private class MyPageAdapter extends FragmentPagerAdapter {
private List<Fragment> fragments;
public MyPageAdapter(FragmentManager fm, List<Fragment> fragments) {
super(fm);
this.fragments = fragments;
}
@Override
public Fragment getItem(int position) {
return this.fragments.get(position);
}
@Override
public int getCount() {
return this.fragments.size();
}
}
}
这是我的片段代码:
package com.Smartz.CoPilot;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import android.graphics.*;
import android.view.View.*;
public class RedFragment extends Fragment implements OnClickListener {
@Override
public void onClick(View p1) {
// TODO: Implement this method
}
public static final String EXTRA_MESSAGE = "EXTRA_MESSAGE";
public static final MyFragment newInstance(String message)
{
MyFragment f = new MyFragment();
Bundle bdl = new Bundle(1);
bdl.putString(EXTRA_MESSAGE, message);
f.setArguments(bdl);
return f;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
String message = getArguments().getString(EXTRA_MESSAGE);
View v = inflater.inflate(R.layout.myfragment_layout, container, false);
TextView messageTextView = (TextView)v.findViewById(R.id.textView);
messageTextView.setText(message);
return v;
}
}
我有一个完整的应用程序,使用了viewpager中的supportMapFragment可以使用一年,自从最新的AIDE更新以来,我无法进行编译。
感谢您提供的任何帮助。
