我在使用gson库时遇到了很多麻烦。构建项目时,我得到:
“无法解析符号gson”
我已经用Google搜索了几个小时,但似乎没有解决方案。这是我的build.gradle文件:
android {
compileSdkVersion 24
buildToolsVersion "28.0.2"
defaultConfig {
applicationId "com.example.jasminkrhan.vaktija"
minSdkVersion 24
targetSdkVersion 24
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:24.2.1'
testCompile 'junit:junit:4.12'
compile 'com.google.code.gson:gson:2.8.2'
}
还有该项目的build.gradle文件:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter {
url "http://jcenter.bintray.com/"
}
}
repositories {
maven {
url "http://repo1.maven.org/maven2"
}
}
dependencies {
classpath 'com.android.tools.build:gradle:2.2.1'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter {
url "http://jcenter.bintray.com/"
}
}
repositories {
maven {
url "http://repo1.maven.org/maven2"
}
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
有人看到我的代码有问题吗? android studio为什么找不到该库?我已经尝试过重启Android Studio,但这无济于事。
答案 0 :(得分:2)
params.permit(:company_id, :customer_id, :name, :del_address1, :del_address2, :del_address3, :del_address4, :del_postcode, :tel, :created_by)
已过时。请使用compile
implementation
您需要在项目级别 build.gradle
中使用这些功能
implementation 'com.google.code.gson:gson:2.8.5'
答案 1 :(得分:0)
尝试将所有存储库全部编写成一个库,并已使用Google依赖项和jcenter中包含的功能,而不要提供URL。像这样:
var questionText = "1 ding ?"
var index = 0;
var num = "";
do
{
num += questionText[index];
} while (questionText[++index] >= "0" && questionText[index] <= "9");
questionText = questionText.substring(num.length);
还有:
buildscript {
...
repositories {
google()
jcenter()
}
}
同样重要的是,由于不推荐使用,所以开始在gradle中使用allprojects {
repositories {
google()
jcenter()
}
}
标签而不是implementation
:
compile
