小编Ven*_*WAR的帖子

昨天,我的应用程序工作正常.

今天,我不知道为什么,在重新打开Android Studio后,应用程序不再编译了.

显示的错误是

Program type already present: com.google.android.gms.internal.measurement.zzwp
Message{kind=ERROR, text=Program type already present: com.google.android.gms.internal.measurement.zzwp, sources=[Unknown source file], tool name=Optional.of(D8)}

我真的不知道发生了什么,我搜索了一切,没有任何效果.如果有人可以帮助我,我真的很感激.我更改了所有依赖项和库以尝试解决它,但没有任何效果.

这是build.gradle项目

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.1'
        classpath 'com.google.gms:google-services:3.2.1'


        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        maven { url 'https://jitpack.io' }
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

这是我的build.gradle模块:app

apply plugin: 'com.android.application'

android …

作为Java JDK10的一部分,JEP307是用于G1实现的并行完整GC.

我试图理解它的描述,但我仍然不相信我的想法是正确的.

我的疑问是它与Concurrent Garbage有关

我有代码播放.ogg音频文件,我从互联网上下载.我没有错误,所以我可以运行它,但随后应用程序崩溃:

package play.my.sound;

import android.app.Activity;
import android.media.AudioManager;
import android.media.SoundPool;
import android.media.SoundPool.OnLoadCompleteListener;
import android.os.Bundle;
import android.util.Log;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnClickListener;

public class PlaySound2Activity extends Activity {
private SoundPool soundPool;
private int soundID;
boolean loaded = false;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    View view = findViewById(R.id.textView1);
    view.setOnClickListener((OnClickListener) this);
    // Set the hardware buttons to control the music
    this.setVolumeControlStream(AudioManager.STREAM_MUSIC);
    // Load the sound
    soundPool = new SoundPool(10, …

文档说“调用者可以通过设置文档 URIEXTRA_INITIAL_URI来指示文档导航器的初始位置。”

但它不会EXTRA_INITIAL_URI在这里解决。我尝试设置为此给出的常量，如注释 ( EXTRA_INITIAL_URI = "android.provider.extra.INITIAL_URI") 中所示，但这不起作用。我该如何解决？

package com.ship.saftwo;
import android.content.Intent;
import android.net.Uri;
import android.os.Environment;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import java.io.File;

public class MainActivity extends AppCompatActivity{
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button button = (Button) findViewById(R.id.button1);
        button.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {navigateToAppDirectory();}});}

    private static final int READ_REQUEST_CODE = 42;
    // adding this does not help: public static final String EXTRA_INITIAL_URI = "android.provider.extra.INITIAL_URI";

    public void navigateToAppDirectory() { …

我正在使用Spring MVC 3.1.0M2并尝试将我的配置移动到java bean.但我遇到以下错误:

我试图从我的项目中完全删除firebase依赖项,但我已经设法完全搞砸了我的gradle,我需要帮助才能让它再次运行.我需要谷歌播放服务依赖,因为我正在使用谷歌地图和地理围栏.这是我每次尝试重建项目时都会遇到的错误.

朋友们

我们要在React JS应用程序中禁用Chrome浏览器中的自动完成功能。我们尝试了互联网上可用的一堆解决方案，但没有任何效果。autoComplete=off不可靠，其他方法也不可靠。

目前这对我们而言确实很重要，因此您能否建议我们采用一种简单的方法来使用React js在Chrome中禁用自动完成功能？

其次，我们为文本框使用一个公共控件/组件，并在各处使用它们

Gradle和Apache Maven之间的主要区别是什么？为什么他们在Android应用程序中受益？

我的 Flutter 项目的 android studio 中缺少 gradle 窗口，但它可用于我的 Kotlin 项目。

我必须生成signing certificate SHA-1以在 Firebase 中注册我的应用程序。

第一篇文章。

我目前正在构建Laravel Nova应用程序。我正在更改仪表板组件-更具体地说是中的文件"resources/js/views/Dashboard.vue"。

我正在努力构建组件-有人知道如何构建组件吗？我有一些代码可以运行webpack.mix以构建我的JS和SCSS文件，但是我很确定它不会在Laravel Nova实例中包含这些文件。

任何帮助都会很棒。

额外：

我已经尝试过从Laravel Nova实例内部运行webpack命令进行构建，但是它出错了。

我有这个字符串:PT0H8M30S."H"前的数字表示小时数,"M"前的数字表示分钟数,"S"前的数字表示秒数....如何使用SQL函数将其转换为分钟数？
结果应该是:8,5分钟

非常感谢!!!!
