無法啓動活力ComponentInfo

-1

我正在嘗試開發Android應用程序來獲取相機數量..但每次我啓動應用程序它說：無法啓動活力ComponentInfo。所以我必須做的解決這個問題..我不知道從哪裏開始！這是我的代碼：無法啓動活力ComponentInfo

清單：

<uses-sdk 
     android:minSdkVersion="19" 
     android:targetSdkVersion="19" /> 
    <uses-feature android:name="android.hardware.camera" android:required="true" /> 
    <uses-permission android:name="android.permission.CAMERA" /> 

    <application 

     android:allowBackup="true" 
     android:icon="@drawable/ic_launcher" 
     android:label="@string/app_name" 
     android:theme="@style/AppTheme" > 
     <activity 

      android:name=".MainActivity" 
      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>

activity_main：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:paddingBottom="@dimen/activity_vertical_margin" 
    android:paddingLeft="@dimen/activity_horizontal_margin" 
    android:paddingRight="@dimen/activity_horizontal_margin" 
    android:paddingTop="@dimen/activity_vertical_margin" 
    tools:context="com.example.test.MainActivity" > 

    <TextView 
     android:id="@+id/tv1" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="@string/hello_world" /> 

</LinearLayout>

的java文件：

package com.example.test; 

import android.app.Activity; 
import android.hardware.Camera; 
import android.os.Bundle; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.widget.TextView; 

public class MainActivity extends Activity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     TextView v = (TextView)findViewById(R.id.tv1); 
     //int x = checkcam(); 
     v.setText(Camera.getNumberOfCameras()); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.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(); 
     if (id == R.id.action_settings) { 
      return true; 
     } 
     return super.onOptionsItemSelected(item); 
    } 
    public int checkcam() 
    { 
     int no =Camera.getNumberOfCameras(); 
     if(no == 1) 
     { 
    return 1 ; 
     } 
     return 2; 
    } 
    }

哪裏是logcat的日誌？ –

你用'int'參數調用'v.setText（）'。將它轉換爲一個'String'。 –

我解決了它

int x = Camera.getNumberOfCameras(); 
     v.setText(String.valueOf(x));
