Java Android：安装 APK 时出错

Android: Error while installing APKs

提问by Lucie P.

I'm slowly trying to do some simple tasks in Android Studio. The following app is installed on emulator without any errors. But when I tried to install it on a real device Redmi 3S this error occured:

我正在慢慢尝试在Android Studio. 以下应用程序安装在模拟器上，没有任何错误。但是当我尝试将其安装在真实设备 Redmi 3S 上时，出现了此错误：

Unknown failure (Failure - not installed for 0)
Error while Installing APKs

I went through similar questions around here but in these cases the error was caused by not enabled debugging, or not accepitng the app instalation. However, I allowed debugging and I also tried to install some other appin Studio and it worked fine.

我在这里遇到了类似的问题，但在这些情况下，错误是由未启用调试或不接受应用程序安装引起的。但是，我允许调试并且我还尝试在 Studio 中安装其他一些应用程序并且它运行良好。

So the question probably is, what's wrong with the code.

所以问题可能是，代码有什么问题。

MainActivity.java

主活动.java

package tlacitko.button;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    public void sendMessage(View view) {
        new Thread(new Runnable() {
            public void run() {

                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        try{
                            URL url = new URL("http://147.32.186.51:8080");
                           // HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
                            InputStream is = url.openStream();
                            BufferedReader br = new BufferedReader(new
                                    InputStreamReader(is));
                            String s = "";
                        }catch(MalformedURLException ex){

                        }catch(IOException e){
                        }
                    }
                });
            }
        }).start();
    }
}

And the xml code:

和 xml 代码：

活动_main.xml

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

I'm now faced with this problem, I have already uninstalled the apk, now I use Android Studio 3.0 want to run apk to Xiaomi MIX 2(Android 7.1.1, API 25), but it failed.

我现在面临这个问题，我已经卸载了apk，现在我使用Android Studio 3.0想运行apk到小米MIX 2（Android 7.1.1，API 25），但它失败了。

$ adb shell pm install -t -r "/data/local/tmp/com.package"
Failure [INSTALL_FAILED_USER_RESTRICTED: Install canceled by user]

And Android Studio tells me "It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing." but I've uninstalled this apk.

Android Studio 告诉我“这个问题可能通过卸载现有版本的 apk 来解决，如果它存在，然后重新安装。” 但我已经卸载了这个 apk。

And I click "OK" button, but it also failed.

我单击“确定”按钮，但它也失败了。

$ adb shell pm uninstall com.package
Unknown failure (at android.os.Binder.execTransact(Binder.java:565))
Error while Installing APK

And finally I find how to solve this problem, I don't turn on "Verify apps over USB", because now this device cannot turn on it until you login xiaomi account, and this is a new device that has not been logged in.

最后我找到了解决这个问题的方法，我没有打开“通过USB验证应用程序”，因为现在这个设备必须登录小米帐户才能打开它，而且这是一个尚未登录的新设备。

Step 1: Go to “Setting” → find “Developer options” in System, and click.

第一步：在“设置”→“系统”中找到“开发者选项”，点击。

Step 2: TURN ON “Verify apps over USB”in Debbuging section.

第 2 步：在调试部分打开“通过 USB 验证应用程序”。

Step 3: Try “Run app” in Android Studio again!

第 3 步：再次尝试在 Android Studio 中“运行应用”！

For me I just made a cleanfor the App then everything works fine.

对我来说，我只是为应用程序做了一个清理，然后一切正常。

It may be your device storage is full. If you are testing on a physical device. However, if you are testing in Emulator then check there also that storage space is available or not. Otherwise, you have to turn-off the Instant Run.

可能是您的设备存储空间已满。如果您在物理设备上进行测试。但是，如果您在模拟器中进行测试，那么还要检查那里的存储空间是否可用。否则，您必须关闭 Instant Run。

I also experienced the same issue when I was installing an app in a new device. This error usually occurs when the app installation is not allowed by the os. This might be because you might not have the authorization to install the app on your phone from just any source.

在新设备上安装应用程序时，我也遇到了同样的问题。当操作系统不允许安装应用程序时，通常会发生此错误。这可能是因为您可能无权从任何来源在手机上安装该应用程序。

So try checking the allow install apps via usbin developer options. If this doesn't work then try revoking all the usb debugging authorizationsand then try installing and provide permission when asked.

所以尝试检查allow install apps via usb开发人员选项。如果这不起作用，请尝试撤销所有usb debugging authorizations，然后尝试安装并在询问时提供权限。

If this also doesn't cut it try disabling instant run as explained in one of the answers above.

如果这也不能解决问题，请尝试按照上述答案之一禁用即时运行。

回答by Catalin

I had the same problem but my issue was lack of space on the device.

我遇到了同样的问题，但我的问题是设备空间不足。

Try this On your device go to Settings -> Device maintenance -> Optimise now

试试这个 在您的设备上转到设置 -> 设备维护 -> 立即优化

Once that is done, try again.

完成后，再试一次。

回答by happy_Coding

Before try all the above suggestion, check enough memory space available in device. This will also reason this problem.

在尝试上述所有建议之前，请检查 device 中有足够的可用内存空间。这也会导致这个问题。

Error: android.os.ParcelableException: java.io.IOException: Requested internal only, but not enough space

错误：android.os.ParcelableException：java.io.IOException：仅内部请求，但空间不足

Happy coding :)
