我的Android应用程序在模拟器中工作正常,但是当我安装.apk并运行时,它说"不幸的是'应用程序'已经停止"

这是androidmanifest.xml

    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.android.baliweather"
    android:versionCode="1"
    android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="21" />
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity android:name=".Main"
              android:label="@string/app_name"
              android:theme="@android:style/Theme.NoTitleBar">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
     <activity android:name=".Prakiraan"
             android:label="@string/app_name"
             android:theme="@android:style/Theme.NoTitleBar">
    </activity>
    <activity android:name=".Update"
             android:label="@string/app_name"
             android:theme="@android:style/Theme.NoTitleBar">
    </activity>
      <activity android:name=".Info"
             android:label="@string/app_name"
             android:theme="@android:style/Theme.NoTitleBar">
    </activity>
</application>

 android.os.NetworkOnMainThreadException

非常自我解释,对吗?您正在UI线程上执行网络任务(HTTP请求等)。你应该在一个单独的线程中运行它。

    private class LongOperation extends AsyncTask<String, Void, String> {

        @Override
        protected String doInBackground(String... params) {
            for (int i = 0; i < 5; i++) {
                try {
                    Thread.sleep(1000);
                } catch (InterruptedException e) {
                    Thread.interrupted();
                }
            }
            return "Executed";
        }

        @Override
        protected void onPostExecute(String result) {
            TextView txt = (TextView) findViewById(R.id.output);
            txt.setText("Executed"); // txt.setText(result);
            // might want to change "executed" for the returned string passed
            // into onPostExecute() but that is upto you
        }

        @Override
        protected void onPreExecute() {}

        @Override
        protected void onProgressUpdate(Void... values) {}
    }

将问题上传到playstore后我遇到同样的问题。

当应用崩溃时,您可以看到两个按钮,强制停止/确定并报告。点击report button,您会在那里找到各种标签。在其中一个选项卡中,您将获得堆栈跟踪。然后你就可以知道你的错误在哪里......

有一次清理项目并重新创建一个apk然后再检查..
