无法从Apk

Question

我需要通过控制packageName检查是否安装了apk。（如powerclean app - ＆gt; app manager - ＆gt; apkFiles）

为此，我需要从apk文件中获取packageName。（不是标签）

我已经尝试过this

了

public void getApkPackage(String pathToApk) {

    Process mProcess = null;
    try {
        mProcess = Runtime.getRuntime().exec("aapt dump badging "+pathToApk);

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

但它返回

ava.io.IOException: Error running exec(). Command: [aapt, dump, badging, /storage/emulated/0/asd.apk] Working Directory: null Environment: null
at java.lang.ProcessManager.exec(ProcessManager.java)
......
Caused by: java.io.IOException: Permission denied
at java.lang.ProcessManager.exec(Native Method)

我已添加

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.GET_PACKAGE_SIZE" />
<uses-permission android:name="android.permission.GET_TASKS" />
<uses-permission android:name="android.permission.PACKAGE_USAGE_STATS" />
<uses-permission android:name="android.permission.KILL_BACKGROUND_PROCESSES"/>
<uses-permission android:name="android.permission.CLEAR_APP_CACHE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INSTALL_PACKAGES"/>
<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />

这些权限。

注意：我不想安装或未安装apk名称，我已经得到了它们。我想得到apk packageName ..

//get app name from apk
public static String getAppLabel(PackageManager pm, String pathToApk ,Context context) {
    PackageInfo packageInfo = pm.getPackageArchiveInfo(pathToApk, 0);

    if (Build.VERSION.SDK_INT >= 8) {
        // those two lines do the magic:
        packageInfo.applicationInfo.sourceDir = pathToApk;
        packageInfo.applicationInfo.publicSourceDir = pathToApk;
    }

    CharSequence label = pm.getApplicationLabel(packageInfo.applicationInfo);
    return label != null ? label.toString() : null;
}

Example

我想做同样的事情。

1 - 获取手机中已有的所有apk路径（系统文件夹除外）

2 - 在手机上获取所有已安装的软件包（已经完成）

从创建的apks路径获取PackageName（问题从这里开始）

4 - 检查已安装包中的每个已创建的apks包名称（简单部分）

5 - 将它们添加到2个arraylist（已安装的apks - 未安装的apks）

试试这个：

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Add respective layout
        setContentView(R.layout.main_activity);

        // Use package name which we want to check
        boolean isAppInstalled = appInstalledOrNot("com.check.application");  

        if(isAppInstalled) {
            //This intent will help you to launch if the package is already installed
            Intent LaunchIntent = getPackageManager()
                .getLaunchIntentForPackage("com.check.application");
            startActivity(LaunchIntent);

            Log.i("Application is already installed.");       
        } else {
            // Do whatever we want to do if application not installed
            // For example, Redirect to play store

            Log.i("Application is not currently installed.");
        }
    }

    private boolean appInstalledOrNot(String uri) {
        PackageManager pm = getPackageManager();
        try {
            pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);
            return true;
        } catch (PackageManager.NameNotFoundException e) {
        }

        return false;
    }

}

Answer 2

public static void getApkPackage(PackageManager pm, String pathToApk) {
    String fullPath = pathToApk;
    PackageInfo info = pm.getPackageArchiveInfo(fullPath, 0);
    Log.i("Package", "PackageName: " + info.packageName + ", VersionName : " + info.versionName );

}

结果：

PackageName: me.pou.app, VersionName : 1.4.73
PackageName: com.elevenbitstudios.twommobile, VersionName : 1.4.3

好的，我找到了答案。我们不需要运行exec来获取未安装＆＃39;的详细信息。 APK。只需使用带有路径的PackageManager.getPackageArchiveInfo，我们就可以获得apk详细信息。

你无法在手机中找到卸载的apk的包名，但你可以手动找到卸载的apk的包名。
