篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了为什么我的win10一开android模拟器就崩溃相关的知识，希望对你有一定的参考价值。
参考技术A 因为安卓模拟器不可以用全部的系统资源，推荐使用凤凰os！应用程序在启动时崩溃-android.view.InflateException：二进制XML文件行＃0：二进制XML
我是android的新手，我创建了一个非常简单的应用程序，通过构建过程没有问题但是当我尝试启动时（无论是在模拟器上还是在我的Android设备中）它崩溃（图像吼叫）。我不确定如何解决这个问题，我检查了logcat，我得到了一些消息，我认为可能指向错误来源，但不知道它们是什么意思。应用程序在我的设备One Plus 3T（android 8.0.0）上的模拟器（PIXEL 2 XL API 27）上崩溃。
Bellow my xml，java代码和日志结果
我的xml布局：
<RelativeLayout

android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
tools:context=".MainActivity"
android:background="#de7905">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/texto_frase_dia"
android:id="@+id/botaoNovaFraseId"
android:layout_alignParentTop="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:layout_alignRight="@+id/botaoNovaFraseId"
android:layout_alignEnd="@+id/botaoNovaFraseId"
android:textSize="@dimen/texto_nova_frase"
android:textColor="#fbfff7" />
我的java代码：
package ie.app.frasedodia;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;

import java.util.Random;
public class MainActivity extends AppCompatActivity {
private TextView textoNovaFrase;
private Button botaoNovaFrase;
private String[] frases = {
"oi",
"tudo bem?",
"ddt?"
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textoNovaFrase = (TextView) findViewById(R.id.textoNovaFraseId);
botaoNovaFrase = (Button) findViewById(R.id.botaoNovaFraseId);
botaoNovaFrase.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Random randomico = new Random();
int numeroAleatorio = randomico.nextInt( frases.length );
textoNovaFrase.setText( frases[ numeroAleatorio ] );
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}

我的gradle设置：
apply plugin: 'com.android.application'
android {

defaultConfig {
applicationId "ie.app.frasedodia"
minSdkVersion 23
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}
答案
这个
Caused by: java.lang.UnsupportedOperationException: Can't convert value at index 2 to dimension: type=0x4
at android.content.res.TypedArray.getDimensionPixelSize(TypedArray.java:730)
让我认为你在@dimen/texto_nova_frase有错误的单位。建议的单位是sp。
