Due to some reasons, it may be necessary to change the domain name specified in the hosts file to the corresponding IP address. Android is a Linux-based system. Similar to Linux, it is set up through the hosts file.

Under Android, /etc is the linux training link to /system/etc. We need to change /system/etc/hosts to achieve this. And this file is read-only and cannot be changed directly through the shell. This can be changed by connecting to a PC using adb. The steps are as follows:

1. Obtain root permissions: adbroot

2. Set /system to be readable and writable: adbremount

3. Copy the hosts file to PC: adbpull/system/etc/hosts

4. Modify files on PC

5. Copy the files on the PC to the mobile phone: adbpush/system/etc/hosts

If you want to check whether the change is successful, you can execute adbshell on the PC and run cat/system/etc/hosts; or run cat/system/etc/hosts on the mobile phone.

In the Android 1.6 system, the hosts file format is a little different from that of PC Linux: one IP cannot correspond to multiple domain names in one line Linux hosts file modification, for example:

127.0.0.1

It is legal on most PC Linux systems, but it does not work on Android 1.6. It needs to be split into one line for each domain name to use:

127.0.0.1

127.0.0.1

127.0.0.1

Solution to changing hosts file and outofmemory under android

You need to use the android emulator to access a website. Although it points to the linux hosts file modification on the development machine, you need to change the hosts file on the andorid,

The website below introduces the techniques

The specific steps are as follows

1. Obtain root permissions: adbroot

2. Set /system to be readable and writable: adbremount

3. Copy the hosts file to PC: adbpull/system/etc/hosts

4. Modify files on PC

5. Copy files from PC to mobile phone: adbpush

/システム/etc/hosts

しかし、Linux仮想ホストの5番目のステップでは、メモリ不足エラーを報(bào)告する人もいます

これはパラメータを追加せずにコマンドラインから直接起動(dòng)したことが原因なので、次のコマンドを使用して起動(dòng)してください

$emulator–avdyouravdname–パーティションサイズ128

Androidエミュレータでhostsファイルを変更する

Android エミュレーターをダウンロードし、解凍して android-sdk-linux_x86 フォルダーを取得します

android-sdk-linux_x86/tools/

./android を?qū)g行してテスト用の仮想電話を作成します

仮想電話を起動(dòng)し、パーティションサイズを128Mに変更します

./emulator-avdtest-partition-size128

新しいターミナルを開き、現(xiàn)在のディレクトリで実行します

./adbpull/system/etc/hosts/home/jecelyin/

hostsファイルをPCに削除

後に実行

./adbrot

./アドレマウント

root権限を取得し、仮想電話上の/systemを書き込み可能として再マウントします

ラップトップ上の /home/jecelyin/hosts ファイルを変更します。ラップトップ上の Web サイトにアクセスするために仮想電話が必要な場(chǎng)合は、ホストの IP アドレスを 10.0.2.2 にする必要があります。
