无法从应用中获取log
这是我的代码:
------------------ -------------的AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<activity android:name=".SecondActivity"
android:process=":hello2">
</activity>
</application>
------------------- ------------ SecondActivity.java
public class SecondActivity extends AppCompatActivity {
protected File mF;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_second);
mF = new File(getFilesDir(), "ss");
}
public void write(View view) {
Storage storage = new Storage("Hello3", 4);
try {
ObjectOutputStream outputStream = new ObjectOutputStream(new FileOutputStream(mF));
outputStream.writeObject(storage);
} catch (IOException e) {
e.printStackTrace();
}
}
public void read(View view) {
try {
ObjectInputStream inputStream = new ObjectInputStream(new FileInputStream(mF));
Storage storage = (Storage) inputStream.readObject();
Log.d("Syuu", storage.name);//Error here.no log output
} catch (IOException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
}
-------------------- Storage.java ----------------
public class Storage implements Serializable {
public String name;
public int id;
public Storage(String name, int id) {
this.name = name;
this.id = id;
}
}
