system directoryにインストールする必要のあるアプリがあります。私はadb commandsを使っていくつかの方法を見てきました。私はこれがPCとUSBケーブル上のadbシェルを使用して行わなければならないと思う。しかし、アプリがDataからsystemにPCを必要とせずに自分自身をコピーする方法はありますか？Androidアプリは、ルートデバイス上のシステムディレクトリに自分自身をコピーできますか？
私が知っているように、Runtimeを使用してアンドロイドアプリ内でコマンドを実行できます。だから、onCreateの中でこのコードを試しましたが、.apkファイルはコピーされません。これはコードです：
boolean isSystemApp = (getApplicationInfo().flags
& (ApplicationInfo.FLAG_SYSTEM | ApplicationInfo.FLAG_UPDATED_SYSTEM_APP)) != 0;
if (!isSystemApp) {
Toast.makeText(getApplicationContext(), "not system app", Toast.LENGTH_LONG).show();
try {
String [] commandsOldVersions = {"adb shell\n", "su\n", "mount -o rw,remount /system\n",
"adb push eyedetection.apk /sdcard/\n", "adb shell\n","su cd /sdcard\n"
, "mv eyedetection.apk /system/app\n","su chmod 644/system/app/eyedetection.apk\n" };
String [] commandsNewVersions = {"adb shell\n", "su\n", "mount -o rw,remount /system\n",
"adb push eyedetection.apk /sdcard/\n", "adb shell\n","su cd /sdcard\n"
, "mv eyedetection.apk /system/priv-app\n", "su chmod 644/system/priv-app/eyedetection.apk\n" };
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR2) {
// for 4.3 and higher versions, execute the following line (because they've changed their system files hierarchies):
Process process = Runtime.getRuntime().exec(commandsNewVersions);
BufferedReader br= new BufferedReader(new InputStreamReader(process.getInputStream()));
Log.i("cmd", br.readLine());
}//end if
else {
//for older version, execute this line instead
Process process= Runtime.getRuntime().exec(commandsOldVersions);
BufferedReader br= new BufferedReader(new InputStreamReader(process.getInputStream()));
Log.i("cmd", br.readLine());
}//end else.
Runtime.getRuntime().exec("adb reboot");
}//end try.
catch (IOException e) {
Log.i("eyedetection", "error in executing adb commands");
}//end catch.
}//end if the app is not system app.
else {
Toast.makeText(getApplicationContext(), "It's system app", Toast.LENGTH_LONG).show();
}
アプリがクラッシュしていませんが、私はlogcatにこれらの行を取得：

私はできませんでした問題をlogcatから把握してください。なぜコードが機能しないのですか？アプリをルートのあるデバイスの別のフォルダに自分自身をコピーさせることは可能ですか、またはusbケーブルを使用する必要がありますか？
root権限を持っていない限り、システムディレクトリにアクセスすることはできません。 – Shahzeb
ルートアクセスとはどういう意味ですか？私のデバイスはrootになっていてsuを走らせることができます。ありがとう。 – Dania
@ Shahzeb私は彼が明示的に彼は手動でそれをadbを使って行うことができると言ったが、それをプログラム的に行う必要があると思う。つまり、アプリは単独でそれを行います。 –
